Question

How does the covalent radius increase in group 7?​

Answer 1

Answer:

Explaining the increase in atomic radius

In each case, the outer electrons feel a net pull of 7+ from the nucleus. The positive charge on the nucleus is cut down by the negativeness of the inner electrons. This is equally true for all the other atoms in Group 7.
