Question
Which of the following statements is incorrect?
But as after removal of the third electron, $P$ gets extra stability due to full filled $s$ orbitals so third ionization energy of phosphorus is lower than that of aluminium.
The first ionization energy of aluminium is approximately the same as that of gallium due to similar charge density.
The second ionization energy of boron is greater than that of carbon because in case of $B$ and electron has to be removed from filled $2 s$ orbitals.
