according to modern definition..
the number of electrons gained or lost or shared to attain the octet in the outermost shell ,gives the combining capacity of the element that is,its valency

What is valency ?
=> Valency is the combining capacity of an atom with another atom (s) .
This is normally given by the number of Valence electrons or by 8 minus the Valence electrons (Only when the number of Valence electrons is more than 4) .
Valency of first 20 elements is given below.
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) Aluminium (Al) = 3
14) Silicon (Si) = 4
15) Phosphorus (P) = 3, 5
16) Sulphur (S) = 2
17) Chlorine (Cl) = 1
18) Argon (Ar) = 0
19) Potassium (K) = 1
20 ) Calcium (Ca) = 2
