Question

Name the properties of the elements which,

decrease in going from top to bottom in a group.

Answer 1

Electronegativity – Decrease in going from top to bottom in a group

1. Electronegativity is a chemical property that explains the tendency of an atom to attract electrons toward itself.
2. It decreases as the atomic number increases, and the gap between the valence electrons and the nucleus grows, resulting in a greater atomic radius.
