Key Points
- Atomic radii- The distance from the centre of the nucleus to the outermost shell containing electrons called the atomic radius.
- While moving left to right across a period in the periodic table, the atomic number increases.
- Due to this the effective nuclear charge also increases.
- This is because the nucleus pull is high for the electrons,
- From right to left in the periodic table the atomic radius increase.
- As Ar is the 18 group element, Cl is the 17 group element, S is the 16 group element, and P is the 15 group element so P has the largest- size ions among these elements.
| Name | Formula | Atomic number |
| Phosphorous | P | 15 |
| Chlorine | Cl | 17 |
| Argon | Ar | 18 |
| sulphur | S | 16 |
