Question

4x The atomic radius of an element
A
decreases
1x
B
increases
when you move from the top to the bottom of a family.

Answer 1

When moving from the top to the bottom of a group (or family) in the periodic table, the atomic radius of an element generally **increases**. This is due to the addition of electron shells as you move down a group, which places the outer electrons further from the nucleus and results in a larger atomic size.

So, the correct statement would be:

- The atomic radius of an element **increases** when you move from the top to the bottom of a family (Group).
