Question

velency if helium????

Answer 1

helium is an inert gas it does not has valency. ook

Answer 2

The helium atom has only the 1s orbital in its only shell, and it is completely filled with 2 electrons. Valency, the combining capacity of an element, is equal to the number of electrons needed, or required to be removed from the outermost shell of the atom of that element, to have a complete 'octet'.
