Match the element to the best description of its ionization energy

Ionization energy, according to chem.libretexts.org, is the quantity of energy that an isolated, gaseous atom in the ground electronic state must absorb to discharge an electron, resulting in a cation. This energy is usually expressed in kJ/mol, or the amount of energy it takes for all the atoms in a mole to lose one electron each.

The answer is b.the gaseous state is electrically positive, while the plasma state is electrically negative.
