Hydrogen has 1 electron in it's valence shell.So it needs to gain 1 more electron to attain a stable state and it should have a negative charge(gain of electrons)then why is it's valency 1+

Expert Answer:

The atomic number and the atomic mass of hydrogen is 1. There is one electron present in an atom of hydrogen. The number of valence electrons present in hydrogen atom is 1. Hydrogen atom loses this electron easily to become stable or to make bonds with other atoms. Thus on losing this one electron, positive ions are formed. Therefore, the valency of hydrogen is +1.
