Question

Explain the factors affecting ionization enthalpy.​

Answer 1

Explanation:

Size of the positive nuclear charge. As the nuclear charge increases, its attraction for the outermost electron increases and more energy is required to remove an electron. ... Size of atom (distance of outermost electron from the nucleus) ... Screening (shielding) effect of inner shell electrons......

hope it helps you dear....

Answer 2

Answer:

The most notable factors affecting the ionization energy include: ... Number of electron shells: if the size of the atom is greater due to the presence of more shells, the electrons are held less tightly by the nucleus and the ionization energy will be less.
