Answer 2

Answer:

HI MATE

valency- it is the the no of electrons an atom loses from its outermost shell

for example- if an element which loses the electron is metal and gain a positive charge and is called cation

similarly the element gaining electron gaining electron is non metal and has a negative charge and is called anion

valence electron - the electron in the outermost shell of an atom is termed as valence electron

for example- the atom fluorine has 7 electron in its outermost shell
