Vedclass · Answer

(C) Electronegativity generally increases across a period from left to right and decreases down a group.Comparing the elements $N$ (Nitrogen),$O$ (Oxygen),and $P$ (Phosphorus):$1$. $N$ and $O$ are in the $2^{nd}$ period,while $P$ is in the $3^{rd}$ period.$2$. In the $2^{nd}$ period,electronegativity increases as $N $3$. $P$ is below $N$ in the same group ($15^{th}$ group),so $N > P$.$4$. Combining these,the electronegativity values on the Pauling scale are approximately: $O (3.44) > N (3.04) > P (2.19)$.Therefore,the correct order is $O > N > P$.

Which one of the following represents the correct order of electronegativity?
