Question

Which of the statement is INCORRECT about electronegativity values?

a Within the period, electronegativity values increasing from left to right.
b Within the period, electronegativity values increasing from right to left.
c Within the group, electronegativity values decreasing from top to bottom.
d Within the group, electronegativity values decreasing from period 1 to period 7

Answer 1

Answer:

Explanation:

Across a period from left to right, atomic number increase, size of atom decreases, effective nuclear charge increases and hence electronegativity increases.

Down the group from top to bottom, size of atom increases, electronegativity decreases, and electropositivity increases. That is why elements at the bottom of a group shows metallic character.

Hence option b is the incorrect statement.
