Question 1 What happens when metals react with chlorine?
Question 2 What happens when metals react with hydrogen?
The 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
The 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.
