Question

metals are arranged in the reactivity series .why hydrogen is kept in the series though it is not a metal​

Answer 1

Explanation:

Although Hydrogen is not a metal it is kept in the reactivity series because like metals, it too loses and electron and becomes positive charged.

Answer 2

Explanation:

Hydrogen being a non-metal is placed in the reactivity series because its reactivity is similar to that of an electropositive element, say metals i.e. can lose electrons to form positive ions. Since hydrogen has one electron in its valence shell, it can lose its electron and become electropositive (H+ )
