Rule 1: Electronegativity increases as we move from left to right
in a period of periodic table.
Rule 2: Electronegativity decreases as we move down a group of periodic table.
a)
Se and Br are in same period. Br is to the right of Se.
So, Br is more electronegative
Answer: Br
b)
B and C are in same period. C is to the right of B.
So, C is more electronegative
Answer: C
c)
Te and S are in same group. S lies above Te.
So, S is more electronegative
Answer: S
d)
Ba and Be are in same group. Be lies above Ba.
So, Be is more electronegative
Answer: Be
