  1. We use the Principle of Charge Neutrality, that is, for an ionic compound to be stable its chemical formula MUST BE NEUTRAL. So you do not need to state the number of cations and anions, you only need to state what they are (and what their charge is).

  2. Magnesium Phosphate is often simply known as magnesium with the chemical formula Mg3(PO4)2. Visit BYJU'S to understand the properties, structure and uses of magnesium phosphate.

  3. Learning Objectives. Know how ions form. Learn the characteristic charges that ions have. Construct a proper formula for an ionic compound. Generate a proper name for an ionic compound. So far, we have discussed elements and compounds that are electrically neutral.

  4. We will need two potassium ions to balance the charge on the sulfate ion, so the proper chemical formula is \(\ce{K_2SO_4}\). Calcium ions have a charge of 2+, while nitrate ions have a charge of 1−.

  5. Learning Objectives. By the end of this section, you will be able to: Define ionic and molecular (covalent) compounds. Predict the type of compound formed from elements based on their location within the periodic table. Determine formulas for simple ionic compounds.

  6. Magnesium phosphate is a general term for salts of magnesium and phosphate appearing in several forms and several hydrates: [ 1 ] Monomagnesium phosphate (Mg (H 2 PO 4) 2). xH 2 O. Dimagnesium phosphate (MgHPO 4). xH 2 O. Trimagnesium phosphate (Mg 3 (PO 4) 2). xH 2 O. Amorphous magnesium phosphate is also claimed. [ 2 ] Trimagnesium phosphate.

  7. Learning Objectives. By the end of this section, you will be able to: Derive names for common types of inorganic compounds using a systematic approach. Nomenclature, a collection of rules for naming things, is important in science and in many other situations.
