| Element | Atomic number | No. of electrons in the valence shell | Group to which the element belongs |
| A | Z - 1 | ||
| B | Z | ||
| C | Z + 1 |

उत्तर
| Element | Atomic number | No. of electrons in the valence shell | Group to which the element belongs |
| A | Z - 1 | ||
| B | Z | 8 | 18 |
| C | Z + 1 |
Since C belongs to group 1 it has less ionization energy than A as atomic size of group 1 elements is more than that of group 17.
