Question

The electronegativity of elements on moving from left to right across a period of periodic table -

A  Depends on the number of valence electrons

B  Remains the same

C  Decreases

D  Increases

​

Answer 1

Answer:

1. on the number of vaence electrons

Answer 2

D. It increases

When we move from left to right across a periodic table the electronegativity increases because of the increase in the nuclear charge.

Hope this helps :)
