Ionization energy (IE) is the energy required to remove the highest-energy electron from a neutral atom. In general, ionization energy increases across a period and decreases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant. chippingham street sheffield

"Web18 uur geleden · You can see that the ionisation energies tend to fall as you go down the Group - although there is a slight increase at lead. The main trend is because: The atoms are getting bigger because of the extra layers of electrons. The further the outer electrons are from the nucleus, the less they are attracted - and so the easier they are to remove. " - Ionisation energy down the group
