24 Ιαν 2017 · The formula would be Mg_3P_2. This would be an ionic compound. First, we know this is an ionic compound because one of the elements is a metal. From the periodic table or from the valence shells of the atoms, we can determine that magnesium forms an ion of +2 charge. Also, phosphorus will form a -3 ion.
Formation of Ions Magnesium and nitrogen react to form an ionic compound. Predict which forms an anion, which forms a cation, and the charges of each ion. Write the symbol for each ion and name them. Solution Magnesium’s position in the periodic table (group 2) tells us that it is a metal. Metals form positive ions (cations).

Describe the energetics of ionic bond formation and breakage. Use the Born-Haber cycle to compute lattice energies for ionic compounds. A bond’s strength describes how strongly each atom is joined to another atom, and therefore how much energy is required to break the bond between the two atoms.
When an ionic compound is formed from magnesium and oxygen, the magnesium ion has a 2+ charge, and the oxygen atom has a 2− charge. Although both of these ions have higher charges than the ions in lithium bromide, they still balance each other in a one-to-one ratio.
A cation (a positive ion) forms when a neutral atom loses one or more electrons from its valence shell, and an anion (a negative ion) forms when a neutral atom gains one or more electrons in its valence shell.
