Vedclass · Answer

(D) In the periodic table,atomic radius generally decreases as we move from left to right across a period due to an increase in effective nuclear charge.$N$,$O$,and $F$ all belong to the $2^{nd}$ period of the periodic table.Their atomic numbers are $N (7)$,$O (8)$,and $F (9)$.As the atomic number increases from left to right,the number of protons increases,which pulls the electrons closer to the nucleus,resulting in a smaller atomic radius.Therefore,the order of atomic radii is $F Thus,the correct increasing order is $F < O < N$.

Which of the following gives the correct increasing order of the atomic radii of $O$,$F$ and $N$?
