4/11/2016. There's no way I would ever rate a box store 5 stars, but I do like our Home Depot. The service isn't always the greatest, but it's usually pretty decent. The have a wide selection and the prices are generally the best in town.
Electrons with the highest energy levels exist in the outermost shell of an atom and are relatively loosely bound to the atom. This outermost shell is known as the valance shell and electrons in this shell are called valance electrons. A completed outermost shell has valance of zero.
Electrons can jump to higher energy levels when they absorb light. An Atom is made of protons, neutrons, and electrons. The electrons circle the nucleus staying within Atomic Orbitals, descrete regions where the electron is most likely to be. Under normal conditions the electrons stay as close to the atom as possible.
