The most common compound containing one calcium atom for every two iodine atoms is simply CaI2, or Calcium Iodide.
Calcium iodide has a total of 3 atoms: 1 calcium atom and 2 iodine atoms.
I believe you mean the formation of the compound calcium iodide. In the formation of calcium iodide, CaI2, the calcium atom transfers two valence electrons to two iodine atoms, with one electron going to each iodine atom. This causes the formation of a calcium ion, Ca2+, and two iodide ions, I-. The electrostatic attraction between the oppositely charged ions forms the ionic bonds that form the compound calcium iodide.
The chemical formula for this compound would be NI3, as there is one nitrogen atom for every three iodine atoms.

The most common compound containing one calcium atom for every two iodine atoms is simply CaI2, or Calcium Iodide.
Calcium iodide has a total of 3 atoms: 1 calcium atom and 2 iodine atoms.
This compound is the calcium iodide - CaI2.
Calcium iodide (CaI2) has two iodine atoms and one calcium atom.
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 you mean the formation of the compound calcium iodide. In the formation of calcium iodide, CaI2, the calcium atom transfers two valence electrons to two iodine atoms, with one electron going to each iodine atom. This causes the formation of a calcium ion, Ca2+, and two iodide ions, I-. The electrostatic attraction between the oppositely charged ions forms the ionic bonds that form the compound calcium iodide.
One calcium atom will transfer one of each of its two valence electrons to one each of two iodine atoms. In the process, the calcium atom becomes a calcium ion with a 2+ charge, and each iodine atom becomes an iodide ion with a 1- charge. The opposite charges between the iodide and calcium ions form an electrostatic attraction called an ionic bond, forming the ionic compound calcium iodide. Ca + I2 ---> I- + Ca2+ + I- ---> CaI2
The formula for calcium iodide is CaI2. This means that the calcium atom has transferred one electron to each of two iodine atoms, for a total of two electrons transferred.
The chemical formula for this compound would be NI3, as there is one nitrogen atom for every three iodine atoms.
Two valence electrons are donated to two I atoms (or one I2 molecule) Ca --> Ca2+ + 2 e- 2 e- + I2 --> 2 I- In this way, taking both together CaI2, calcium iodide, is formed.
