during the formation of calcium iodide,calcium donates two of its +ve ions each to a fluorine atom(2 in number) thereby making its octet and also fulfills the octet formation of each of fluorine atom..
A calcium ion (Ca2+) loses two electrons from an atom to achieve a stable octet electron configuration. This results in a +2 charge on the calcium ion.
A calcium atom will readily form Ca2+ ions while a chlorine atom will readily form Cl- atoms. Thus, ionic bonding is the only bonding that can occur between a calcium and a chlorine atom. The equation for the reaction is as follows: Ca + Cl2 --> CaCl2
In the compound calcium iodide, one calcium atom transfers 2 electrons to one iodine atom. This results in both atoms achieving a stable electron configuration – calcium with a full outer shell and iodine with a complete octet.
Ca3N2 has a Lewis structure that starts with a Calcium atom in the center. From this Ca atom, there are two single bonds, each connected to a Nitrogen atom. Each nitrogen atom then has a double bond with a single Calcium atom.

One atom of calcium donates two electrons to one atom of oxygen during the formation of the compound CaO. Calcium loses two electrons to achieve a stable octet configuration, while oxygen gains two electrons to complete its outer shell.

Calcium has twenty electrons in each atom.
An octet of electrons is when the outermost electron shell of an atom contains eight electrons.
Calcium is an element, so each atom of calcium is calcium.
Technically, any atom could have 40 electrons, but it would have a very weird charge. However, Zirconium has 40 electrons without being an ion.
20 (any more or less and it would be an ion not an atom)
It'll have to lose two to have a stable octet.
