Explanation:
CASE I
- When the elements are in same group, then the electronegativity decreases when we go from top to bottom.
- Eg.- K, Na, Li, H (increasing order of electronegativity)
CASE II
- When the elements are in same period, then the electronegativity increases when we go from left to right.
- Eg.- Al, Si, P, S (increasing order of electronegativity)
Cheers!!
