which has the highest ionization energy? (hint: remember the octet rule. if an element already has its perfect octet, does it want to gain or lose electrons?) neon (ne) chlorine (cl) sodium (na) tungsten (w)

Answer

Brief Explanations:

Ionization energy is the energy required to remove an electron from an atom. Neon is a noble - gas with a full octet in its outer shell. It is very stable and does not want to lose electrons, so it has a high ionization energy. Chlorine needs to gain one electron to achieve an octet, sodium easily loses one electron to achieve an octet, and tungsten is a metal that can lose electrons relatively easily compared to a noble - gas.

Answer:

Neon (Ne)
