Hydrogen period number and group number
WebSimilarly, hydrogen has +1. But in Metal Hydrides, such as NaH, LiH, etc, it has -1 Some elements have the same oxidation states as in their compounds such as Halogens have -1 except when they form a compound with one another or Oxygen. Alkali Metals such as Na, K, Rb, Li, Cs have +1 Alkali Earth Metals have +2 such as Mg, Ca, Ba, Be, Sr, etc
