Across a peiod, the atomic radius decreases gradually.

Thus, a noble gas will have the smallest radius in a period!

Thus, Statement I is wrong, and the answer is option D.

siril: I'm sorry, i couldn't explain the statement II, but since it is true; you can remember it as a fact.

shruti8761: but you are false with 1st one. because i think you should do this with vandervalls radius

siril: I have a long form periodic table with me, i verified with it

siril: The atomic radius decreases along a period

siril: And down the group, it increases

shruti8761: but the radius of noble gases is an exceptional case
