How do metals react with hydrogen? Explain with an example.

Class 10th Lakhmir Singh & Manjit Kaur - Chemistry 3. Metal and Non-Metal

Answer :

Hydrogen do not generally react with any metals. However only few very reactive metals reacts with Hydrogen to form metal hydrides. For example: Sodium Hydride is formed when Hydrogen gas is passed over heated sodium.
