$\huge \underbrace \pink{★ Answer❀✿°᭄★}$

The valency of the atom of an element is determined by the number of electrons in its outermost shell, i.e. valence shell. For atoms with less than 4 or less electrons in the valence shells (i.e. valence electrons), valency = no. of electrons. For atoms with more than 4 valence electrons, valency = 8

Answer 2

Answer:

The valency of the atom of an element is determined by the number of electrons in its outermost shell, i.e. valence shell. For atoms with less than 4 or less electrons in the valence shells (i.e. valence electrons), valency = no. of electrons. For atoms with more than 4 valence electrons, valency = 8 - (no.
