Select the incorrect statement out of the following
Energy required to remove an electron from an isolated gaseous atom ‘x’ in its ground state is called ionization energy or enthalpy.
X + E → X++e-;
E is 1st ionization energy or enthalpy.
Here E' stand for 2nd ionization enthalpy.
2nd ionization enthalpy of an element is always smaller than the first one.
As the effective nuclear chare increases, second ionization energy is greater than first ionization energy as the effective nuclear charge increases
