Hi! Could someone explain why B is the answer instead of C. I picked C because it has the least amount of electrons but with a higher atomic mass which would give a higher attraction between the valence electron in the nucleus giving a higher ionisation energy
Thanks in advance!
The answer is B because element W is Neon (noble gas). Those have the highest ionisation energy because its extremely difficult to “steal” an electron away from them:)
Also, I understand your reasoning if we were to choose between C or E, but a higher atomic mass doesnt necessarily indicate more protons - could be more neutrons too. Therefore, the force of attraction between the electrons and nucleus doesnt have to be higher in B compared to E.
Hope it makes sense:)
Oh yess it could be more neutrons haha, thanks for correcting me, it’s probably because when it has a FULL outer shell, it’s much harder to remove it from the shell. Thank you so much:))
