None of these

Vedclass · Answer

(D) In the periodic table,atomic radius decreases across a period from left to right due to an increase in effective nuclear charge. Oxygen $(O)$ is in Group $16$ and Period $2$. Fluorine $(F)$ is to the right of oxygen in the same period,so its atomic size is smaller than oxygen. Neon $(Ne)$ is a noble gas in the same period,but its atomic radius is generally considered larger than oxygen due to the van der Waals radius,but in terms of covalent radius,it is not typically compared directly. However,looking at the options provided,$F$ is smaller,and $Ne$ is a noble gas. Actually,moving down a group increases size. Since no element from the same group below oxygen is provided,and $F$ is smaller,the correct answer is none of these.

Which element has a larger atomic size compared to oxygen $(O)$?
