There are two energy sublevels in the second principal energy level. These two energy sublevels are 2s and 2p. The energy distribution in an atom is divided into a number of principal energy levels, and the principal energy levels are again divided into four basic energy sublevels.
Know MoreThe sublevels are s (sharp), p (principle), d (diffuse) and f (fundamental). The s sublevel can hold two electrons, and the p sublevel can hold six electrons. Therefore, the second principal energy level can hold a total of eight electrons in the 2s and 2p sublevels. Eight is the maximum number of electrons that the second principal energy level needs to fill its octet.

Full Answer >Hydrogen can have an infinite number of energy levels, based on the principle of quantum mechanics. These energy levels are represented by the quantum number "n".
Full Answer >The number of electrons present in a given energy level depends on the element. The formula for determining the electron capacity for each energy level is "two times n squared," where n is equal to the number of the level.
Full Answer >There is a potential maximum of 50 electrons in the fifth energy level of an atom. The formula for determining the maximum number of electrons in any energy level is two times n squared, where n is the energy level.
