Covalently Bonded Polyatomic Ions

|Acetate||C2H3O2- or CH3COO-|
Above is a table of common covalently bonded polyatomicContaining two or more atoms. ions. Lewis structures for these ions can be draw just as they can for neutral compounds, the difference being that the number of electrons do not balance out the nuclear charges of the atomsThe smallest particle of an element that can be involved in chemical combination with another element; an atom consists of protons and neutrons in a tiny, very dense nucleus, surrounded by electrons, which occupy most of its volume. involved. A significant number of ionic compounds contain polyatomic ions, so it is important class of ions to be familiar with.
