Let"s look come the periodic table because that our answer! The periodic table tells us information around every facet in visibility in its neutral state. The neutral state of an atom is as soon as it"s net charge is zero; that is, the number of protons amounts to the numbers of electrons. Oxygen is the eighth element in the periodic table, v the price O. This means that it has actually eight electrons in the neutral state. Because it is neutral, it likewise has eight protons!

The regular table has an additional number connected with every element, and that is it"s atomic mass.

You are watching: Number of protons neutrons and electrons in oxygen

for oxygen, the atomic mass is 16 AMU (Atomic massive Units). In regards to mass, protons and also neutrons have about the same mass, and also electrons have actually very little mass in comparison. Protons and neutrons each counting for one AMU, and also the electron counts because that zero AMU. So, if the atom mass of oxygen is 16, that method we have a total of 16 protons and neutrons. 16 complete protons and neutrons minus 8 protons pipeline us v 8 neutrons.

This calculation can gain surprisingly tricky! The atomic mass the an aspect is an mean over all of the isotopes of every element. An isotope is an aspect that has a different number of neutrons in various atoms. The chemical properties that the aspect don"t change, yet the atomic mass that the facet is different if that has, say, 8 neutrons matches 9 neutrons. Because the atomic mass of each element is average over every stable isotope of that element, periodically we see decimal numbers because that the atomic mass. For example, the atomic mass that carbon (the 6th element top top the regular table) is 12.01 AMU. This tells us that most carbon atoms have actually 6 protons and also 6 neutrons, and some carbon atoms have actually 6 protons and maybe 7 or 8 neutrons.

Most carbon atoms have actually 6 protons and 6 neutrons, for this reason the atomic mass is very close come 12 AMU. Researchers have found the family member abundance of each element and isotope, so we canlook increase how common an isotope is. For oxygen, the isotope with 8 protons and also 8 neutrons makes up 99.7% of all oxygen atoms, for this reason its a safe bet come say the oxygen nearly always has actually 8 protons and 8 neutrons.

Answer 2:

I"ll begin by comment the question directly: in general, element oxygen has actually 8 protons, 8 neutrons, and also 8 electrons. Your inquiry is an exciting one, because it is frequently the beginning point for countless other questions we deserve to ask around elements, chemicals, and also materials.

For instance, despite we often refer to the gas us breathe as just "oxygen", that is in reality the molecule O2 (two oxygen atom bonded together).

The factor for this has to do v the variety of electrons oxygen has. Electrons have actually a certain method of arranging us on atoms, and we can think of electrons as existing in "shells" approximately the atom"s nucleus. For currently we can think of atom as having actually "inner" and "outer" shells. Oxygen has an inner covering that deserve to hold 2 electrons, and also an external shell that can hold 8. Shells space filled from the innermost to the outermost, therefore since oxygen has 8 electrons, we put 2 in the inside shell, and also the continuing to be 6 in the outer shell. as we can see, there"s still 2 empty spots for electrons to go in the external shell (which have the right to hold 8), and also the oxygen would really favor to to fill those spots. The does this in a clever way; it looks because that a partner! If two oxygens get together, they have actually 16 electron total. By "sharing" 4 that them, lock each obtain to "keep" fifty percent of the remaining electrons (16 total - 4 shared = 12 remaining, 12/2 = 6 each). On every oxygen, 2 of this 6 walk in the inside shell, and the various other 4 walk in the outer shell. Now, the oxygens move close together, and they re-superstructure the 4 continuing to be electrons that they didn"t "keep". This means they both get to feel prefer they have a complete outer covering (4 the they have to themselves, 4 that are shared between them). This is the O2 gas that you and also I breathe!

This is simply one instance of the varieties of points that counting electrons deserve to predict. Often, the variety of electrons in an aspect can tell us about the what color it could be, whether or not it"s a magnet, or what types of other elements it will certainly react with. Also, if you ever want to know how numerous protons and also electrons one more element has, it"s as simple as looking in ~ the atomic number top top the regular table (the big number in the optimal of the box for each element). That number tells you the variety of protons an facet has, and also by extension tells girlfriend the number of electrons the has. Elements space charge neutral (meaning the charges add up come 0), and also since protons have a hopeful charge, each proton is well balanced out by 1 electron, which has a an adverse charge. The situation with neutron (which have actually no charge) have the right to be a little much more complicated, but the variety of neutrons is often the very same as or similar to the number of protons.

Answer 3:

This is answered pretty totally on ubraintv-jp.com here. One refinement is to consider ions, whereas the answers in ~ the linked question considers only neutral oxygen atoms. In general, the energy of one atom will certainly be lower, climate the valence (outermost) electron shell is full. For almost all elements, this method gaining or losing electrons to various other atoms, thus developing ions.

while the neutral oxygen atom has actually 8 total electrons, 2 room in the innermost (s) covering while the valence shell, which deserve to hold 8 electrons, has actually only 6. Thus, oxygen often tends to gain 2 electrons, for a total of 10 electrons. This results in an atom through a net charge (i.e., one ion).

Answer 4:

In one oxygen atom, there are 8 protons and also 8 electrons. Most oxygen atoms additionally have 8 neutrons, yet it is feasible for an oxygen atom to have actually 9 or 10 neutrons. Castle are simply rarer. The oxygen we breathe is no in atom form. That is in its molecular form, i beg your pardon is two oxygen atom joined with each other by bonds, and also between its two atoms, this molecule has 16 protons, 16 electrons, and also most typically 16 neutrons.

Answer 5:

An oxygen atom consists of eight protons.

A neutral oxygen atom will also contain eight electrons, but it is feasible for one oxygen atom to it is in ionized, in which instance it will certainly have much more or fewer (up to ten, or under to zero), relying on how it became ionized.

Oxygen has actually several isotopes, and also they have different numbers of neutrons. The most common isotope that oxygen is oxygen-16, which has eight neutrons; however, oxygen-18 is also reasonably common, and also it has ten neutrons. Both of these isotopes room stable (i.e. Not radioactive).

Oxygen-17 (nine neutrons) is also stable, but is rarer. Having actually too numerous neutrons, or as well few, will make the oxygen isotope radioactive, yet still oxygen.

Answer 6:

Oxygen is #8 in the regular table. That means it has actually 8 protons and also 8 electrons. The variety of neutrons varies according to the isotope: the steady isotopes have actually 8, 9, or 10 neutrons(Wikipedia).

Did you know that this is the international Year the the routine Table - IYPT? One funny thing people are doing is detect the aspect that is the very same number as their age. Following year my age will it is in the very same number together Tungsten.

Here"s an article around the IYPT from a chemistry magazine i get: check out it here.

Answer 7:

Generally, there space 8 protons, 8 neutrons and 8 electrons in the most abundant oxygen molecule. Here"s wherein it gets progressed and cool! as soon as Oxygen loses or gains neutrons it i do not care an isotope. Oxygen isotopes are seldom occurring and have advantageous applications. Because that example, brain imaging in hospitals provides Oxygen 15, comprise 7 neutrons.

Answer 8:

An oxygen atom usually has 8 protons, 8 neutrons, and also 8 electrons. Looking in ~ the regular table, oxygen has atomic number 8 and atomic weight 15.999. The atomic number tells you how numerous protons room in the atom"s nucleus. This identify the atom.

because that example, if the atom number to be 7, then the atom would certainly be nitrogen, v 7 protons in that nucleus. The atomic nucleus has both protons and neutrons, but the amazing thing is the there aren"t constantly an equal number of neutrons and also protons. This information is revealed in the atom weight, which is a number that refers to the mean mass the the cell core (in atomic mass systems or amu). If every one of the oxygen atoms we know about, always had 8 protons and also 8 neutrons, then the atomic weight would certainly be 16. Yet we recognize that some creates of oxygen have actually fewer than 8 neutron in your nucleus, and that is why the atomic load is a little bit less than 16. Oxygen"s 8 electrons space negatively charged, and also they orbit the atom nucleus and balance the optimistic charge the the 8 protons. The hopeful charge of 1 proton precisely cancels the negative charge the 1 electron.

Answer 9:

Oxygen is atom number 8 on the routine table, which means it has actually 8 protons! This means that a neutral oxygen atom will have actually 8 electrons (but this number deserve to change! for example, throughout chemical reactions molecules can lose and also gain electrons). The variety of neutrons relies on the isotope, however a secure isotope will normally have either 8, 9, or 10 neutrons.

Answer 10:

Thanks for her question, and also let’s begin with the basics: just how chemical facets aredefined, specifically on the routine table that elements.

The major, entirety numbers over the elements on the periodic table of elements (you’veprobably checked out one in your science instructor’s room) determine the element and it describes the number of protons together a definitional part of the element’s identity. It is the lengthy version the this straightforward fact: oxygen will constantly have 8 protons, whether on Mars, Pluto, Earth, yesterday, or the job after tomorrow.Next, let’s think about the variety of neutrons and electrons in oxygen: in short, they’rechangeable within natural constraints. In the situation of neutrons, oxygen has various isotopes, i beg your pardon are different versions the oxygen that keep their variety of protons, but readjust their number of neutrons. In our scientific observations, oxygen has either 8, 9, or 10 neutrons.

Now, in terms of electrons, oxygen need to contain 8 electrons in stimulate to it is in isoelectric, which is a means of saying the electrons equal the variety of protons, rendering no fee to the oxygen atom, and also this is taken into consideration the most natural state of the oxygen atom (you can “add”/”subtract”electrons by high energy collisions with fragment accelerators, but that’s an ext artificial, anddepending top top the referral point, oxygen can “gain” electrons during molecular bonding).
