1. If a second-period diatomic molecule has 8 electrons in its valence shell (total of 2s and 2p electrons), what is the predicted bond order of the molecule?
2. If a second-period diatomic molecule has 14 electrons in its valence shell (total of 2s and 2p electrons), what is the predicted bond order of the molecule?
3. If the total number of electrons in a homonuclear diatomic molecule is 18, what is the overall bond order of the molecule? Enter your answer as a decimal number.
