Which of the following statement is correct?

Options

A. `X^(-)` ion is larger in size than X atom
B. `X^(+)` ion is larger in size than X atom
C. `X^(+)` ion is larger in size than `X^(-)` ion
D. `X^(+) and X^(-)` ion are equal in size

Answer

A

Explanation

`X^(-)ion` larger in size than `X` atoms . Because of low effective nuclear charge on `X^(-),X` has a bigger size .
