Lead (IV) chloride is an ionic compound. Lead (IV) cation has a 4+ charge, while chloride ion has a 1- charge, so they combine to form an ionic compound with a formula of PbCl4.
This compound is not known today; the probable formula is FrCl.
Copper chloride is an ionic bond, where copper has a positive charge and chloride has a negative charge, resulting in them being attracted to each other and forming a bond.
Chloride is always minus one (-1).
The ionic name for aluminum chloride is aluminum (III) chloride. The Roman numeral III indicates that aluminum has a +3 charge in this compound.
The name for AlCl3 in the ionic form is aluminum chloride. It typically forms ionic compounds with a 3+ charge on the aluminum cation and a 1- charge on the chloride anion.
Francium chloride is a radioactive chemical compound with the formula FrCl. It is predicted to be a white solid and is soluble in water. Its properties resemble caesium chloride. It is produced by the reaction of hydrochloric acid with francium metal. Source: Wikipedia
The ionic compound formed between Chloride (Cl-) and Mg2+ is MgCl2. In this compound, the magnesium ion with a 2+ charge combines with two chloride ions with a 1- charge to achieve a neutral overall charge.
Magnesium chloride is an neutral ionic compound. In neutral ionic compounds, the positive charge of the cations must balance out the negative charge of the anions. In the case of magnesium chloride, magnesium is the cation with an ionic charge of +2 and chlorine is the anion with an ionic charge (each) of -1. Since two chlorine anions together have a charge of -2 total, they balance out the one magnesium cation with a charge of +2.
