Question

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

Solution

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)

  Is there an error in this question or solution?
