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

What's the use of iota in valency ?
iota is √-1 ,
hai sexy
hey mate can you please tell me why phosphorus have two valency 3,5
please
yeah but electrons can only gave up-to 3 electrons
I understand 3 but don't get 5?
mate can you tell?
