Sodium will give out 1 electron, oxygen will accept 2 electrons, chlorine will accept 1 electron, and aluminum will give out 3 electrons.
Group 13 elements typically lose 3 electrons to form a +3 ion.
Group 1 elements lose 1 electron to become ions with a +1 charge.
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.
Sodium will give out 1 electron, oxygen will accept 2 electrons, chlorine will accept 1 electron, and aluminum will give out 3 electrons.
Group 13 elements typically lose 3 electrons to form a +3 ion.
Group 1 elements lose 1 electron to become ions with a +1 charge.
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 has 56 electrons. To make 8 electrons, it would need to lose 48 electrons to reach a stable electron configuration similar to a noble gas.
It will lose 2 electrons.
