Question

Why is the valency of hydrogen positive?


Solution

Definition of positive valence

1: the valence of a positively charged ion

2: the number of electrons an atom can give up sodium has a positive valence of 1
Hydrogen has one valence electron, so to be stable, it can gain or lose one electron. When hydrogen meets a more electronegative element, it forms a positive charge (losing one electron), but when it meets a less electronegative element, it forms a negative charge (gaining one electron).
