Reaction of metal with chlorine and hydrogen

Question 1 What happens when metals react with chlorine?

Question 2 What happens when metals react with hydrogen?

Reaction of metal with chlorine

Metals react with chlorine to form ionic chlorides.
2Na(s) + Cl₂ (g) —–> 2 NaCl(s)

Ca (s) + Cl₂ (g) —–> CaCl₂

Mg (s) + Cl₂ (g) —-> MgCl₂

Reaction of metals with hydrogen

Most of the metals do not combine with hydrogen.Only a few reactive metals like sodium,potassium,calcium and magnesium react with hydrogen to form metal hydrides.
