What is the valency of Lithium? Correct Answer 1

Valency is the combining power of an element. Elements in the same group of the periodic table have the same valency.

Key Points

  • Valency is the no of electron that looses, shared or gain to achieve stability or we can say to complete it outer most shell. 
  • If any element has valence electron (electrons present in outer most shell) less than 4
    • ​​Valency = no of valance electron (valence electron<4)
  • If any element has valence electron ​more than 4
    • ​​Valency = 8 - no of valance electron (valence electron>4)

​For Lithium:

  • Li(Z=3) Electronic configuration = 2, 1
    • Valency = no of valance electron  = 1

​Hence, we can conclude that 1 is the valency of Lithium.
