ionization energy does not depend on
Answers
Answer:
The ionization energy increases as each electron is removed. Ionization energies are dependent upon the atomic radius. ... The more electrons shielding the outer electron shell from the nucleus, the less energy required to expel an electron from said atom. The higher the shielding effect the lower the ionization energy.

a) Its nuclear charge
b) the shielding effect
c) electron neutrality
d) penetration effect
Answer:
The ionization energy of an element does not depends on electron neutrality.
Explanation:
Ionization energy:
- The least amount of energy needed to liberate the most loosely bound electron from an isolated gaseous atom, positive ion, or molecule is known as the Ionization energy (IE).
- In physics, Ionization energy is often measured in electronvolts (eV) or joules(J).
- In chemistry, The energy required to ionize a mole of atoms or molecules.
- The units of Ionization energy is expressed as kilojoules per mole (kJ/mol) or kilocalories per mole (kcal/mol).
Factors effecting Ionization energy:
Atomic size:
The Ionization Potential decreases as atomic size increases. The outermost electrons of an atom travel farther away from the nucleus as it grows larger, and the nucleus loses its attraction to those electrons, making them easier to remove.
Nuclear charge:
Ionization potential rises as nuclear charge between the outermost electrons and the nucleus (effective nuclear charge, or Z ) rises.
Screening effect:
Ionization potential decreases as the screening effect on the outer electrons increases because they are less attracted to the nucleus and are easier to remove.
Penetration effect:
Subshell penetration and orbital stability with partial and complete filling.
