WebMay 27, 2014 · Polyatomic ions are formed when a group of atoms have a charge. Hydroxide, for example, is formed when oxygen and hydrogen covalently bond but still have a charge of -1. When a polyatomic ion forms an ionic bond with another ion, a polyatomic ionic compound is made. For example, the +1 barium ion can form an ionic bond with …

WebA 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-). WebCovalent bonds meanwhile usually occur between non-metals. As long as the individual atoms can form an octet of electrons from sharing electrons in a covalent bond, there's always a possibility. So nitrogen for example is a non-metal with 5 valence electrons and needs 3 more for an octet, and can form a variety of covalent bonds. job description of employee
