This document contains information about common ion charges in chemistry. It lists the charge for many common ions such as halides (-1), sulfides (-2), nitrates (-1), and groups 1 and 2 metals (+1 and +2 respectively). It also indicates the multiple possible charges for transition metals such as iron (+2 or +3), copper (+1 or +2), and chromium (+2 or +3).
