The size of Cl^(-)=1.81ÅandCl=0.99Å. Explain |
|
Answer» Solution :1 `Cl-1s^(2)2s^(2)2p^(6)3s^(2)3p^(5),Cl^(-)-1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)` 2. Generally anions are LARGER than their parent atom 3. `Cl^(-)` had 18 electrons and Cl has 17 electrons. The later EXPERIENCES an greater effective inward pull by the nucleus. 4. This DECREASES the size of Cl atom when compared to `Cl^(-)` ion. |
