What is ionization energy?
What is ionization energy?
- The energy released when an electron is added to an atom
- The minimum energy needed to remove a valence electron (correct)
- The amount of energy required to add a valence electron
- The energy released when an electron is removed from an atom
Why does ionization energy increase across a period?
Why does ionization energy increase across a period?
- As the number of electron shells increases (correct)
- Because the distance between the nucleus and electrons decreases
- Due to a decrease in the number of protons
- Because the negative force on electrons weakens
