| Reactions of Hydrogen |
| Hydrogen does not react with water, acids or bases. |
 Reactions with oxygen |
| A mixture of hydrogen gas and air will not react unless ignited with a spark or flame, in this case the result is a fire or explosion whose only product is water. |

| Reactions with halogens |
| Hydrogen gas reacts with fluorine to produced hydrogen(I) fluoride. |
