What trend do you note for the atomic radii of the third period?

As you move across the period, the atomic radii decreases.
This is because of an increase in the number of protons (and electrons) and therefore, an increase in the nuclear charge.

Answer:
The atomic radii decreases from left (sodium) to right (Argon).
Explanation:
The number of positive protons in the nucleus increases so the pull on the electrons increases and this decreases the radius.
