Which of these have no unit? — Periodic Table and Periodicity Chemistry Question

💡 Solution & Explanation

Electronegativity is the measure of the tendency of an atom to attract the bonding pair of electrons towards them. Electronegativity has no units because all elements are compared with most electronegative atom fluorine. Electron affinity is the amount of energy released on the addition of an electron to the neutral gaseous atom and the unit is 1 kJmol . Ionization energy is the amount of energy required to remove an electron from a neutral gaseous atom and the unit is 1 1 kJmol or kcalmol . Excitation potential is the amount of energy required for an electron to jump from the ground stat
