उत्तर
The particular with lowest ionization potential in a group will ionize most easily.
For example among elements of group 1 Value of ionization potential is:
| Element | Li | Na | K | Rb | Cs |
| Ionization energy KJ mol-1 |
520 | 496 | 419 | 403 | 375 |
Cesium (Cs) has lowest ionization potential value which is 375 KJmol-1. So it will ionize most easily.
Concept Insight :
Lesser is the ionization potential value; more easily is the tendency to form a cation.
