The first ionisation potential is maximum for

What is the definition of ionization energy for an atom?

Consider the elements $Ne$,$Na$,and $Mg$. The element with the highest first ionization enthalpy and the element with the lowest second ionization enthalpy,respectively,are:

How many ionisation energies can carbon have?

The first ionisation energies (in $kJ \ mol^{-1}$) of four consecutive elements of the second period are given in the options. The first ionisation energy of nitrogen is

The correct trend in the first ionization enthalpies of the elements in the $3^{rd}$ period of periodic table is:
