| Reactions of Barium |
| Reactions with water |
| Barium reacts readily with water to form barium hydroxide and hydrogen gas. |
| Ba(s) + 2H2O(g)Ba(OH)2(aq) + H2(g) |
| Reactions with air |
| Barium metal is covered with a thin layer of oxide that helps protect the metal from attack by air, but to a lesser extent than the corresponding layer in magnesium. Once ignited, barium metal burns in air to give a mixture of white barium oxide and barium nitride. |
