Answer:

Let M represents an alkali metal.

2M+H

2

→2MH

MH can be represented as M

+

+H

In this reaction, conversion of hydrogen an be represented as H

2

+2e

→2H

Thus, a molecule of hydrogen accepts a pair of electrons to form 2 hydride ions. Gain of electrons is reduction. Hence, hydrogen is reduced to hydride ions.

Note: Alkali metal is oxidised to M

+

ions.

Answer:

Alkali metals is oxidized to m+ions

Explanation:

2M+H2--2MH

MH can be present m plus plus h minus in this reaction conversion of the hydrogen can be represented as H2 + 2 c minus is equal to 2 h - does a molecule of hydrogen accepts a pair of electrons to form two ions gain of electrons is reduction
