a)
Na is in group 1 of periodic table.
So, it has 1 valence electron.
It can loose that electron and form ion with +1 charge
Answer: +1
b)
Ba is in group 2 of periodic table.
So, it has 2 valence electrons.
It can loose those electrons and form ion with +2 charge
Answer: +2
C)
Ga is in group 3 of periodic table.
So, it has 3 valence electrons.
It can loose those electrons and form ion with +3 charge
Answer: +3
d)
Pb is in group 4 of periodic table.
So, it has 4 valence electrons.
It can loose those electrons and form ion with +4 charge
Answer: +4
