Sodium lose one electron, aluminium lose three electrons.Chlorine accept one electron, oxygen accept two electrons.
Al, Ga, and In each lose 3 electrons. Its easy to remember, because there are three of them and they each lose three electrons. The other elements in group 13 vary
Group 1 elements a.k.a. Alkali metals lose 1 electron to form 1+ ions
It will not lose any electron. As it is a noble gas (Group 18 ) it will not either gain or lose or share any electrons. It has a completely filled shell. So there is no need for losing electrons. They are also called as 'Inert Gases'.
Groups determine the number of electrons on the outer shell of an atom. When elements react, they want to complete their outer most shell. Filling the outer most shell is called the octet rule. In the cases of groups 1, 2 and 3, they want to donate, 1, 2 or 3 electrons to lose the outer most shell and form a completed outer shell.
Group 2A elements typically lose 2 electrons when forming ions.
Group 2 elements lose 2 electrons to achieve a stable electron configuration.

Polonium can lose two or four electrons.
It will not lose any electron. As it is a noble gas (Group 18 ) it will not either gain or lose or share any electrons. It has a completely filled shell. So there is no need for losing electrons. They are also called as 'Inert Gases'.
I am not sure what you mean by atoms, i think you mean electrons (part of an atom).Calcium is in Group 2 of the periodic table so this means that in order to become stable it will lose 2 electrons.

it will lose 3 electrons
Barium loses 2 as it is in group 2 and it's easier to lose two than to gain more than this.
It will lose 2 electrons.
