Polyatomic Ions graded A+ already passedA polyatomic ion is a charged particle which has two or more atoms held together by covalent (sharing of pairs of electrons) bonds Some rules: 1. Ions that end in ate have oxygen in them. 2. Elements in the same family make similar ions. So for example if you know chlorate, you also know bromate and iodate too (BrO3-, and IO3-). There are some exceptions. Nitrate is not like phosphate even though nitrogen and phosphorus are in the same group. However ar...
