Atomic radii decreases as we move from ...

Atomic radii decreases as we move from left to right of periodic table. Justify your answer .

Text Solution

Verified by Experts

(i) As we move along the period , the shell number remains same but the number of protons increases .
(ii) increases positive charges impose strong attraction over electrons and thus the electron cloud shrinks towards the nucleus which results in decrease in atomic size .
