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

उत्तर
Metals generally do not react with hydrogen. But some reactive metals like sodium, potassium, calcium and magnesium can force the hydrogen atom to accept the electrons given by them and form salt-like ionic solid compounds called metal hydrides.
For example:
2Na(s) + H2(g) → 2NaH(s)
