Hello friend,
smallest element in period 3 in size is Argon, because the number of electrons present is more than any other element of period 3 so the nuclear charge is also more than others. And the more nuclear charge the smaller size.
Hope it helps

Answer:
Argon (Ar)
Explanation:
Argon is the smallest atom of the Period 3 because it has 18 number of electrons that is also equal to 18 number of protons due to which the force of attraction between electrons and protons increases and their size thus decreases.
Hope it helps you ❤️
