Why Valence Is Always A w
hole Number​

Answer 1

$\huge\red{\mid{\fbox{\tt{Answer:-}}\mid}}$

Valency of an atom is the number of electrons donated or taken up in the formation of bond. Valency is always a whole number because number of electrons donated or shared cannot be fractional. For example Cl atom , its valence electronic configuration is 3s23p5 , it requires one electron to complete its octet.
