Calcium obeys the octet rule by donating its two valence electrons to some more electronegative atom(s) to form a calcium cation with the same electronic configuration (although, of course, not the same electric charge) as the element neon, which has an octet of valence electrons.
Forming Calcium(II) ion, the calcium atom gives away two electrons and obtains the octet in the third energy level.
It gains electrons!
Cl
H
Yes it does
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..
if it is a noble gas it already has an octet, otherwise, it would need to gain or use electrons to complete an octet and would no longer be neutral or unbounded.
No it is not fully obeying the octet rule. Boron has only 6 electrons (3 own + 3 from each F atom), lacking two for the octet. Fluorine is 3x satisfied, each with 8 electrons (each has 7 own plus 1 from boron).
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.
Sodium would LOSE 1 electron to satisfy the octet rule.

Na atom ion has an electronic configuration 2,8,1 On losing one electron it forms Na+ cation, with the configuration of 2,8 thereby obeying octet rule.

No it is not fully obeying the octet rule. Boron has only 6 electrons (3 own + 3 from each F atom), lacking two for the octet. Fluorine is 3x satisfied, each with 8 electrons (each has 7 own plus 1 from boron).
No, quite the opposite. An octet of electrons would make the atom stable, and therefor unlikely to react with most elements.
Calcium has twenty electrons in each atom.
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.
An octet of electrons is when the outermost electron shell of an atom contains eight electrons.
Sodium would LOSE 1 electron to satisfy the octet rule.
It becomes a calcium cation - Ca2+
Calcium is an element, so each atom of calcium is calcium.
when the outer most shell of an atom was said to have 8 electrons then it was said to possess an octet
