D. argon (Ar), a noble gas
Explanation:
- Argon is the element on the third period with the highest first ionization energy.
- Ionization energy is a measure of the readiness of an atom to lose an electron.
- Weakly held electrons in the valence shell are easier to lose compared to the inner shell electrons.
- Across a period, ionization energy increases and since Argon is a noble gas on the periodic table, it has the highest first ionization energy.
- The energy required to remove electron from a filled orbital or inert-gas configuration is very great.
