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 >The fourth principal energy level in the standard atomic model differs from the three preceding levels in that it is the first level onward to have an f-sublevel and orbitals. The number of electrons that can occupy the fourth level obeys the two-n-squared occupancy rule, 32 electrons.
Full Answer >An energy level is the measurement of discrete energy a subatomic particle, such as an electron, can absorb. When light or other energy strikes an atom, it can transfer some of that energy to its particles, raising their energy level.
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.
