Lithium has a smaller atomic radius than potassium, explain why.
Lithium has less energy levels than potassium.
Lithium has more energy levels than potassium.
Lithium has more protons than potassium.
Potassium has a smaller atomic radius
Nitrogen has a smaller ionization energy than antimony. Explain why.
Nitrogen has more energy levels than antimony. Therefore, the electrons are farther from the nucleus and it requires more energy to remove these electrons.
Nitrogen has less energy levels than antimony. Therefore, the electrons are close to the nucleus and it requires more energy to remove these electrons.
