What is the number of electrons in the outermost energy level?


Answer by  Brokencheese (14)

The number of electrons (also known as valence electrons) are located in the outermost energy level of any given electron. the first energy level or "orbit" can have a maximum of 2 electrons, the next can have up to 8 (total of 10) the third, fourth, sixth, and all else have up to 8 electrons each.

The number of electrons in the outermost energy level of an atom will depend completely on the type of element you are interested in. The position of the element in the period table can then be used to determine the number of electrons in the outermost energy level.

It depends on the atom/ion of which you want to know the number of electrons. It varies from element to element.


Answer by  anrimala36 (208)

Electrons in the outermost energy level, or shell, are called "valence electrons." The actual number of them depends on their position on the periodic table, the same for each column.


Answer by  fishy (1085)

The number varies since the number of electrons varies for every element. The outermost orbital or energy level will react with other elements or compounds to fill its outer shell.


Answer by  willard (874)

When you write out the electronic configuration of an atom(1s^2 2p^3... ), the first number indicates the principal quantum number, or energy level of the electron. The outermost electrons have the largest principal quantum number and the superscript tells you how many electrons are in that level.
