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.
an electron can have.An electron that is as close to the nucleus as it can be. is in its lowest energy level.The farther an electron is from the nucleus,the. higher the energy level that the electron occupies.The difference in energy. between two energy levels is known as a quantum of energy.
