Which one of the following is expected to have largest size?A. `F^(-)`B. `O^(-2)`C. `Al^(+3)`D. `N^(-3)` |
|
Answer» Correct Answer - D Due to having three atomic size increases . `F^(-) = 9+1 = 10` electrons, `O_(-2) = 8+2=10` electrons `Al^(+3) = 13-3 = 10` electrons `N^(3-) = 7+3 =10e^(-)` Because electrostaic force between nucleus and `bar(e)` cloud is least in nitrogen. |
