The facets that belong to the noble gases or inert gases or (Group VIII-A) have the highest possible ionisation energy. If we were to take it a solitary element then Helium is said to have actually the highest very first ionization energy amongst all the other neutral elements. The ionization potential is claimed to it is in 24.5874 eV.

You are watching: Which element has the highest first ionization energy?

However, we additionally need to think about that the inert gases space basically steady or the have actually a secure octet state. What this method is that the halogens would then showcase the highest possible ionization energy. We deserve to say that after helium and also Neon Fluorine has the highest ionization energy among the halogen elements.

Meanwhile, if we look in ~ the regular table we can notice two main ionization energy trends.

What happens is the the ionization energy always decreases together you relocate from the height of the graph to the bottom (Column).Ionization energy increases as you relocate from the left side of the chart to the ideal side (Row).

So among the easiest techniques to identify ionization power is to uncover the elements’ placements on the routine table. As pointed out above, elements closer to the top and towards the appropriate of the routine table will have greater ionization energies.
