Watch out! Lightning is extremely dangerous. A solitary bolt that lightning can bring a exchange rate volts that electricity. That"s enough energy to irradiate a 100-watt bulb for 3 months! As superior as that is, lightning is nothing more than a sudden flow of extremely tiny particles. What room the corpuscle that flow in a lightning bolt? The answer is electrons.

What are Electrons?
Electrons are one of three main species of corpuscle that make up atoms. The various other two varieties are protons and also neutrons. Unlike protons and neutrons, i beg your pardon consist of smaller, easier particles, electrons are an essential particles that do not consist of smaller sized particles. They space a type of basic particlecalled a lepton. Every leptons have an electrical charge of \(-1\) or \(0\).
Properties of Electrons
Electrons are very small. The mass of one electron is only around 1/2000 the mass of a proton or neutron, therefore electrons contribute virtually nothing to the total mass of an atom. Electrons have an electric charge of \(-1\), i beg your pardon is equal but opposite come the charge of a proton, i m sorry is \(+1\). Every atoms have actually the same number of electrons together protons, so the confident and an unfavorable charges cancel out, making atom electrically neutral.
Where space Electrons?
Unlike protons and neutrons, which are located inside the nucleus in ~ the facility of the atom, electron are discovered outside the nucleus. Due to the fact that opposite electrical charges attract each other, an adverse electrons room attracted come the hopeful nucleus. This pressure of attraction keeps electrons constantly relocating through the otherwise empty an are around the nucleus. The figure listed below is a common means to represent the structure of one atom. It shows the electron together a bit orbiting the nucleus, similar to the way that planets orbit the sun. However, this is an untrue perspective, together quantum mechanics demonstrates that electrons are much more complex.
What"s Your energy Level?
Electrons are located at fixed ranges from the nucleus, dubbed energy levels. You deserve to see the an initial three energy levels in the number below. The diagram likewise shows the preferably possible variety of electrons in ~ each power level.
