An ion is an atom of a chemical element that has an unequal number of electrons compared to protons. Remember that electrons are negative charges, and protons are positive charges. In the case of the calcium ion, we have a calcium element with a positive charge of 2. Positively charged atoms are called cations.

Calcium iodide (chemical formula CaI2) is the ionic compound of calcium and iodine. This colourless deliquescent solid is a salt that is highly soluble in water. Its properties are similar to those for related salts, such as calcium chloride.

For example, a neutral calcium atom, with 20 protons and 20 electrons, readily loses two electrons. This results in a cation with 20 protons, 18 electrons, and a 2+ charge. ... The name of a metal ion is the same as the name of the metal atom from which it forms, so Ca2+ is called a calcium ion.

Determining Chemical Properties using the Periodic Table. Chemical properties of each element are determined by the element's electronic configuration, and particularly by its outermost valence electrons. ... In addition, the total number of electron shells an atom determines which period it belongs to.

The third shell carries on filling up only after 2 electrons are in the 4th shell. So what happens in calcium is that 8 of the remaining 10 electrons are in the 3rd shell, and the other 2 are in the 4th shell.
