Why is the ionization potential of Nitrogen (atomic number 7) greater than that of Oxygen (atomic number 8)?
  1. Because nitrogen is more stable than oxygen as its outermost valence shell is half-filled
  2. Because nitrogen is less stable than oxygen as its valence shell is half filled
  3. Because nitrogen is more stable than oxygen as its outermost valence shell is completely filled
  4. Because nitrogen is more stable than oxygen as its valence shell is half filled
