Calcium Iodide (CaI2)
As an element iodine is 'I2' and calcium is 'Ca'. However, in combination it CaI2 ( Calcium Iodide.
The chemical formula for the compound formed between iron(III) and iodine is FeI3 (iron(iii) iodide).
The calcium atom will transfer its two valence electrons, one to each of two iodine atoms, to form the compound calcium iodide, CaI2.
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

Covalent bonds are formed between non-metals only, while ionic bonds are formed between metals and non-metals. Since calcium is a metal and iodine is a non-metal, this would not be a covalent bond.
Calcium iodine is formed when calcium reacts with iodine. Ca(s) + I2(s) --> CaI2(s)
Water is the compound. Iodine and calcium are elements, and air is a mixture.

This compound is the calcium iodide - CaI2.
calcium iodide will be formed and also carbon dioxide
Ca + I2 --> CaI2 Each calcium gives up 2 electrons to iodine when forming calcium iodide.
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.
