A calcium atom becomes stable by achieving a full outer electron shell, which contains 8 electrons. Calcium has 20 protons, so it typically forms ions by losing 2 electrons to achieve an electron configuration like that of a noble gas.
If a calcium atom loses 2 electrons, it will form a calcium ion with a positive 2 charge (Ca^2+). This ion will have a stable electron configuration similar to that of a noble gas, making it more stable than the neutral calcium atom.
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..
The bond between calcium and carbon in calcium carbide is an ionic bond.
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 oxide atom is composed of one calcium (Ca) atom and one oxygen (O) atom. These two atoms combine through ionic bonding to form the compound calcium oxide (CaO).

Calcium is an element, so each atom of calcium is calcium.
If a calcium atom loses 2 electrons, it will form a calcium ion with a positive 2 charge (Ca^2+). This ion will have a stable electron configuration similar to that of a noble gas, making it more stable than the neutral calcium atom.

The bond between calcium and carbon in calcium carbide is an ionic bond.
A calcium atom typically loses two electrons to form a calcium ion with a 2+ charge. The loss of these electrons allows the calcium ion to achieve a stable electron configuration similar to that of a noble gas.

A calcium oxide atom is composed of one calcium (Ca) atom and one oxygen (O) atom. These two atoms combine through ionic bonding to form the compound calcium oxide (CaO).
The compound formed when chlorine and calcium combine is calcium chloride, which has the chemical formula CaCl2. In this compound, each calcium atom loses two electrons to achieve a stable electron configuration, and each chlorine atom gains one electron to reach a stable state.
The valency of fluorine in calcium fluoride is -1. Calcium has a valency of +2, so the formula for calcium fluoride is CaF2. Each calcium atom donates two electrons to each fluorine atom, resulting in a stable ionic compound.
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.
I believe it is 2, seeing it is a metal, and has 2 valence electrons. Correct me if I'm wrong, I don't have my periodic table with me (Calcium -> Ca?).
