  • Photosynthesis diagrams worksheet answers part 1Levels of Energy: All the research on atomic structure and the hideously difficult-to-understand properties of electrons come together in the topic of "electron energy". An atom such as lithium has three electrons in various orbitals surrounding the atomic center. These electrons can be bombarded with energy and if they absorb enough of the quanta of energy being transferred they jump about and in the most extreme case, leave the lithium atom completely. ,In the case of the nitrogen(IV) oxide molecule, the formula is NO2. Nitrogen is from group V and has five valence electrons. Oxygen is from group VI and has six valence electrons. Total valence electrons = 5 + 6 +6 = 17. This is an odd number, so there has to be an unpaired electron somewhere. Bond strength
