Question:

Gallium has an abnormal value of atomic radius. Why?

Answer:

➡️It is a well known fact that on moving down the group of p-block elements, the atomic radius is expected to increase. However, gallium is an exception. ... It is due to the presence of additional 10 d-electrons in gallium which offer poor screening effect for the outer electrons from the increased nuclear charge.
