Vedclass · Answer

(C) Electronegativity increases across a period from left to right and decreases down a group. In the periodic table,$O$ (Oxygen) is in group $16$ and period $2$,$N$ (Nitrogen) is in group $15$ and period $2$,and $P$ (Phosphorus) is in group $15$ and period $3$. Comparing these,$O$ has the highest electronegativity due to its position at the far right of period $2$. $N$ has a higher electronegativity than $P$ because $N$ is in period $2$ while $P$ is in period $3$ (electronegativity decreases down a group). Therefore,the correct order is $O > N > P$.

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