Question

what is justification energy? why are second & third ionization enthalpies of the elements higher than the first ionization enthalpy​

Answer 1

Answer:

Second ionisation enthalpy is always greater than the first ionisation enthalpy. After the removal of first electron, the atom changes into monovalent positive ion (M+). In the ion (M+), the number of electrons decreases but the nuclear charge remains the same as the parent
