0.9) Explain the factors affecting atomic radius.Puolain expanded octet with example. |

Answer» Factors affecting atomic radius are: 1. Nuclear charge: As the nuclear charge increases, it pulls all the electrons closer to the nucleus resulting in the decrease of the atomic size (atomic radius). 2. Number of filled shells: Increase in the number of filled shells, the valence electrons will be far away from the nuclear attractions and hence it increases the atomic radius. 3. Screening effect: Increase in the number of filled inner shells would increase the screening effect that is intervening electrons screen the valence electrons from the nuclear attraction and increases the atomic radius. |
