The ions should form CaCl2 because the two chlorine atoms each take an electron from calcium to form the chloride ion Cl-, and the calcium becomes Ca2+ ion.
The formula unit for calcium nitride is Ca3N2. That would be 3 atoms of calcium and 2 atoms of nitrogen, for a total of 5 atoms in a formula unit.
Ca + Cl2 --> CaCl2 or Ca2+ + 2 Cl- --> CaCl2
Calcium chloride (CaCl2) is commonly used in equations instead of calcium chloride (CaCl) because CaCl2 is the correct chemical formula for the compound. Calcium chloride exists as a diatomic molecule composed of one calcium atom and two chlorine atoms. Using the correct formula ensures accurate representation of the chemical species involved in a reaction.
There are 14 chlorine atoms in seven sodium chloride formula units. This is because each sodium chloride formula unit contains one chlorine atom, so in seven units there are 7 x 1 = 7 chlorine atoms.
The formula is CaCl2. It represents one atom of calcium bonded to two atoms of chlorine. This compound is known as calcium chloride.
There is no correct chemical formula described in your question. When calcium and chlorine combine, they form calcium chloride with a formula of CaCl2.
Chlorine atoms, which are present as chloride ions.

calcium and chlorine atoms
If two chlorine atoms attract electrons from two calcium atoms, they will form ionic bonds. The chlorine atoms will gain one electron each to achieve a full outer shell, forming chloride ions, while the calcium atoms will lose two electrons each to become calcium ions. The resulting compound will be calcium chloride, with the formula CaCl2.
Calcium chloride is CaCl2; the subscript of chlorine is 2.
Sodium chloride (NaCl) formula unit has one chlorine atom.
The ions should form CaCl2 because the two chlorine atoms each take an electron from calcium to form the chloride ion Cl-, and the calcium becomes Ca2+ ion.
The formula unit for calcium nitride is Ca3N2. That would be 3 atoms of calcium and 2 atoms of nitrogen, for a total of 5 atoms in a formula unit.
Ca + Cl2 --> CaCl2 or Ca2+ + 2 Cl- --> CaCl2
Calcium chloride with formula CaCl2 has molecular mass of 141. Commercial calcium chloride has formula CaCl2,2H2O.It's molecular mass is 177.
