Question

what is the example of valency

Answer 1

The valency of an atom is equal to the number of electrons in the outer shell if that number is four or less. Otherwise, the valency is equal to eight minus the number of electrons in the outer shell. Once you know the number of electrons, you can easily calculate the valency.

Valence electrons are the electrons located at the outermost shell of an atom. ... For the oxygen atom, you can see that the outermost shell has 6 electrons, so oxygen has 6 valence electrons. Neon's outermost shell has 8 electrons.

Answer 2

Valency is the no. Of electrons that is needed for an octet configuration. So example of valency : hydrogen's valency is 1 because it needs one more electron to fill the last shell completely.
