Hydrogen is not a metal but it has been assigned a place in the metal reactivity series. Why?

Text Solution

Verified by Experts

The reactivity of metals is measured with the tendency of the metal to lose their electrons. Since hydrogen also has a tendency of losing an electron and forming a positive ion, it has been assigned a place in the metal reactivity series.
