Define the term ‘ionisation potential`.
What do you understand by successive ionization energies?
Name the periodic property which relates to the amount of energy required to remove an electron from an isolated gaseous atom.
A, B, C are three elements in which B is an inert gas other than helium.With this information complete the following table.
| Element | Atomic number | No. of electrons in the valence shell | Group to which the element belongs |
| A | Z - 1 | ||
| B | Z | ||
| C | Z + 1 |
Also, explain the following : Ionization energy of element C is less than that of element A.
State whether the ionization potential increases or decreases on going down a group.
