Question

The factors that influence the ionization energy are:

• A. Size of the atom
• B. Charge of the atom
• C. Size and charge of the atom
• D. Size, charge, and type of electron involved (s, p, d, or f)

Hint:

The factors affecting ionization energy include the nuclear charge, atomic size and the electron type. The ionization energy increases left to right due to nuclear charge, and decreases as you go down a group, because there are more shells that shield the outermost electrons. s-electrons are harder to remove than p-electrons.

Answer 1

The Correct Option is D

Ionization energy, the energy to remove an electron from a gaseous atom,
is determined by these factors:
• Atomic Size: Smaller atoms exhibit higher ionization energy due to stronger nuclear attraction.
• Nuclear Charge: Increased nuclear charge strengthens the nucleus-electron attraction, elevating ionization energy.
• Electron Type: S-orbital electrons, being less shielded than p, d, or f electrons, are more challenging to remove.
For instance, elements within the same period typically show rising ionization energy with increased nuclear charge.
