• B. bigger than
• C. smaller than
• D. None of the above

Answer 1

The correct option is B bigger than

Anions are atoms or group of atoms that have gained electron. Since, they now have more electrons than proton, they carry a negative charge. Since they have additional electrons , therefore, the size of an anion is bigger than that of the present atom. For example ; Chloride anion $\left(C{l}^{-}\right)$, Bromide$\left(B{r}^{-}\right)$, Iodide$\left(I^{-}\right)$, etc.
