MgI2 is magnesium iodide. Magnesium is divalent, it forms the Mg2+ ion, iodine forms the I- ion.
The number of protons and neutrons does not change when an ion forms.
When an element forms a negative ion, the name changes to IDE, fir example: chloride
A 2+ ion of boron is not commonly found, as boron usually forms a 3+ ion. Strontium typically forms a 2+ ion by losing two electrons.
As an alkali metal francium form the cation Fr+. A specific name doesn't exist. Transformation in a cation involve the loss of an electron.
The sulfate ion is SO42-. Elements in group 16 form anions with a charge of 2-, for example oxygen forms the oxide, O2- anion.
It forms the Na+ ion.
Phosphorus usually forms compound negative ions as PO3-3 phosphite ion and PO4-3 phosphate ion in some cases P-3 phosphide ion also exists as in Ca3P2 as a positive ion phosphorus forms PH4+1 phosphonium ion.
Sodium ions have a charge of 1+
Water disassociates to form the OH- ion or the hydroxide ion, and the H3O+ ion, otherwise known as the hydronium ion.
Ca2+ is a cation formed by Calcium to become stable and attain the noble gas configuration of Argon. Calcium forms this cation by losing two electrons
