Atomic number
Which statement is correct with respect to halogens​

Answer 1

Answer:

Answer

The electronic configuration of nitrogen N(7)=2,5

Phosphorous P(15)=2,8,5

N is more electronegative than P.

From top to bottom down a group, electronegativity decreases. This is because number of shell increases down a group, and thus there is an increased distance between the valence electrons and nucleus, or a greater atomic radius.
