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.
Maximum number of electrons in an energy level. Each energy level of an atom could only accomodate a certain number of electrons. The maximum number of electrons that can populate a certain energy level is given by the following formula.where n = the specific energy level. 1  The maximum number of electron in the first energy level (n = 1) is 2 (1) 2 = 2 electrons. The maximum number of electron in the fifth energy level (n = 5) is 2 (5) 2 = 50 electrons. 2  The maximum number of electron in the sixth energy level (n = 6) is 2 (6) 2 = 72 electrons. 3  The maximum number of electron in the seventh energy level (n = 7) is 2 (7) 2 = 98 electrons.
