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

You are watching: Which of these elements has the highest first ionization energy

However, we likewise need to think about that the inert gases are basically stable or the have actually a stable octet state. What this means 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 possible ionization energy amongst the halogen elements.

Meanwhile, if we look at the routine table we can notification two key ionization energy trends.

What wake up is the the ionization energy constantly decreases as you relocate from the height of the graph to the bottom (Column).Ionization power increases as you move from the left side of the graph to the right side (Row).

So among the easiest techniques to identify ionization energy is to find the elements’ placements top top the routine table. As pointed out above, facets closer come the top and towards the ideal of the regular table will certainly have greater ionization energies.
