Sketch a graph to show how

\log_{10}

(Ionization energies for chlorine (atomic number

17

) varies when the plotted against number of electron removed.

Accepted Answer

The successive ionization energy is defined as the energy required to remove the first, second, third etc. electrons from the ion such as that 1 mole of gas with 1+ ion gives 2+ ions. The successive energies are dependent on the number of electrons present in the atom originally.
The electronic configuration of the Chlorine atom is $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{5}$

The first ionisation energy is labelled as low energy because the last electron is in the p-orbital, and it is unstable, so the removal of an electron is very easy.
The 7 electrons from the outer shell of the chlorine atom are the first to be removed.
The 8 electrons from the next shell of the chlorine atom are the next to be removed.
Finally, the two electrons from the inner shell of the chlorine atom are removed with very high energy.
