Answer 2

Answer:

The valency when defined in terms of hydrogen is the number of hydrogen atoms that can combine with or replace one atom of the element.

Explanation:

Since the valency of Hydrogen is 1. It can either gain one electron to complete the nearest noble gas configuration or loose the electron.

Must know:

Hydrogen resembles with both alkali and halogens.

If it gains one electron => Halogens.

If it loses one electron => Alkali metals.
