Front

What happens to atomic radius as you move from left to right across a period?

Back

Atomic radius decreases as you move from left to right across a period.

Front

Why does atomic radius decrease from left to right across a period?

Back

The atomic radius decreases due to increased nuclear charge, which pulls electrons closer to the nucleus.
