why do noble gases have high ionization energies? they have low atomic numbers they have a full outer shell of electrons they have fewer protons they are highly reactive
Answer
Brief Explanations:
Noble gases have a full outer - shell of electrons, which gives them a stable electron configuration. Removing an electron from a stable configuration requires a large amount of energy, thus they have high ionization energies.
Answer:
They have a full outer shell of electrons
