Answer 1

valecy bw 1 to 4 fix two types electro and covalency
ON lies bw N-8 to N n= no. of valence e
variable gernelly for amphoteric substances

Answer 2

→ Can be defined as the combining capacity of an element.

→ Valency is only a number doesn't have positive and negative signs.

→ It cannot be zero.

→ It may be variable but variation is limited to only two variables.
