Ionisation energy depends upon:

Which electronic configuration corresponds to least ionisation energy?

Ionisation energy of hydrogen is

Ionisation energy is highest for:

The ionisation energy (IE_(1)) of an atom is defined as the energy needed to remove an electron from gaseous atom in its ground state. The 2nd ionisation energy (IE_(2)) is the additional energy needed to remove the 2nd electron and so on. The successive ionisation energy of any species is increasing always. Generally, the first ionisation energy increase along a period. But there are some exceptions. One which is not an exception is:
