Valency shell electrons number = group number for s block or p block elements in the periodic table = total electrons in the outer most shell or quantum number
Valence shell is the outermost shell or the outer most energy state of the atom of that element.
S Block :
Group 1 : Hydrogen (1s¹), Lithium (2s¹), Sodium (3s¹) etc. : 1
Group 2: Helium(1s²), Beryllium (2s²), Magnesium (3s²) etc. : 2
P block elements
Group 3: Boron (2s² 2p¹ ), Aluminium ( 3s² 3p¹) etc : 3
Group 4: Carbon (2s² 2p²), Silicon (3s² 3p²) etc : 4
Group 5: Nitrogen (2s² 2p³ ), Phosphorus (3s² 3p³), etc. : 5
Group 6: Oxygen (2s² 2p⁴ ), Sulfur (3s² 3p⁴) etc : 6
Group 7: Flourine (2s² 2p⁵) , Chlorine (3s² 3p⁵) etc : 7
Group 8: Neon (2s² 2p⁶), Argon (3s² 3p⁶) etc : 8
