Phosphorus, P , is a group 15 element and therefore forms 3- anions. The process of naming ternary ionic compounds is the same as naming binary ionic compounds.4. A polyatomic ion is formed when a neutral molecule gains or loses electrons, just as ions are formed when neutral atoms gain or lose electrons. Similarly, chlorine is in group 7, so it forms the Cl − anion, which is the chloride ion. Thus, a nitrogen atom will The hydroxide ion must thus carry a single negative charge. Using the rules described in Section 3.5. b. Polyatomic Ion: Chlorate. We can simply refer to the cation in the ionic compound as magnesium.

Exercise 5. Common Polyatomic Ions. Step 1: Figure out how many electrons the molecule must have, based on the number of valence electrons in each atom. Because it is an anion, we add the suffix -ide to its name to get phosphide as the name of the ion. Bentuk T E. As a result, a polyatomic ion is a group of covalently bonded atoms with a net charge because the total number of electrons in the molecule does not equal the total number of protons in the molecule. To balance the positive and negative charges, we look to the least common multiple—6: two iron 3+ ions will give 6+, while three 2− oxygen ions will give 6−, thereby balancing the overall positive and negative charges., Ca(OH) 2, Ba 3(PO 4) a. The formula is thus Na 2 SO 4. A B The cation is the magnesium ion, and the anion, which contains oxygen, is sulfate.
