1)Electrons revolve in orbits of specific radius around the nucleus without emitting radiation
2)Within each orbit, each electron has a fixed amount of energy; electrons in orbits further from the nucleus have greater energies
3)An electron may 'jump' from one orbit of high energy to another of lower energy causing the energy difference to be emitted as a photon of electromagnetic radiation such as light
4) An electron may absorb a photon of radiation and jump from a lower-energy orbit to a higher-energy one.

- Starting with lead oxide, describe how you can prepare lead chloride. (Solved)
Lead chloride is an insoluble salt so it is prepared by double decomposition. So basically we must come up with a soluble salt from the lead oxide, the mix it with another soluble chloride to form the lead chloride.
