Chapter 5
Periodic Properties:
atomic radius
size of the electronic cloud, increase with Z. Decrease with the groups and up the periods
ionic radius
cations are smaller and anions are bigger w.r.t. the corresponding atom. Also rFe2+ > rFe3+ (since fe2+ hasone more e-)
-
-
electron affinity
energy released after one mole of atoms captures one mole of electrons. Increase with the groups and up the periods.
ionization potential
energy required to extract one mole of e- from a mole of isolateed atoms. Increase with the group and up the periods.
Also: second ionization energy > first I.E.

-
Acidity and Basicity
acidity increase with the groups and up the periods, basicity decrease in the same ways.
