Based on the electron-dot diagram for neon, why does neon have a very high ionization energy compared to the other elements in period 2?

Neon has a complete octet, making it stable and requiring more energy to remove an electron.

Neon has fewer protons than other elements in period 2, resulting in higher ionization energy.

Neon has a larger atomic radius, which increases ionization energy.

Neon has a lower electronegativity, leading to higher ionization energy.
