When Li loses one electron it achieves Noble gas configuration.
Removal of second electron from Li requires much additional energy.
When Be loses two electrons it achieves nobe gas configuration.
Li : 1s(2) 2s(1) ---> 1s(2) hence easy to remove first electron but difficult to remove the second
Be: 1s(2) 2s(2) ----> 1s(2) 2s(1)----> 1s(2)
First step filled orbital hence difficult to remove first electron; but loosing second electron gives Noble gas configuration hence easier to remove that.
Ca2+ > K+ > Cl- > S2-
Higher positive charge makes it difficult to remove electrons hence higher ionization energy.
Higher negative charge makes it easier, hence lower ionization energy.
