In its compounds, gallium occurs mainly in the +3 oxidation state, and rarely in the +1 oxidation state. Besides the normal salts formed with halogens, chalcogens, etc., gallium easily forms organogallium compounds. Alkylgalliums are liquids at room temperature and quite flammable. Pure gallium metal costs about US$0.40 per gram.
