What is valency ?

=> Valency is the joining limit of an iota with another molecule (s) .

This is ordinarily given by the quantity of Valence electrons or by 8 less the Valence electrons (Just when the quantity of Valence electrons is more than 4) .

Valency of initial 20 components is given beneath.

1) Hydrogen (H) = 1

2) Helium (He) = 0

3) Lithium (Li) = 1

4) Beryllium (Be) = 2

5) Boron (B) = 3

6) Carbon (C) = 4

7) Nitrogen (N) = 3

8) Oxygen (O) = 2

9) Fluorine (F) = 1

10) Neon (Ne) = 0

11) Sodium (Na) = 1

12) Magnesium (Mg) = 2

13) Aluminum (Al) = 3

14) Silicon (Si) = 4

15) Phosphorus (P) = 3, 5

16) Sulfur (S) = 2

17) Chlorine (Cl) = 1

18) Argon (Ar) = 0

19) Potassium (K) = 1

20 ) Calcium (Ca) = 2

tanishq972003: hey mate can you please tell me why phosphorus have two valency 3,5
tanishq972003: please
tanishq972003: yeah but electrons can only gave up-to 3 electrons
tanishq972003: I understand 3 but don't get 5?
tanishq972003: mate can you tell?
