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 orbit around the nucleus. -Each orbit has a fixed energy called an energy level. -To move from one energy level to another, an electron must gain or lose just the right amount of energy. -Each energy level has a different energy. -The further from the nucleus the energy level is, the more energy it has. Con: Electrons bounce around, not orbit.
