Energy level four (shell N) can hold 32 electrons. The maximum number of electrons for any energy level can be calculated using the formula Electron Capacity = 2(n x n), where n is the energy level.
There are six electron shells, and these have the following letter classifications: K, L, M, N, O and P. The electron capacity for each shell is as follows: K=2, L=8, M=18, N=32, O=50 and P=72. An electron shell at one of the six energy levels does not have to be full before electrons start occupying the next level. The Periodic Table details the electron configuration for elements.Learn More
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.Full Answer >
The third energy level of an atom, referred to as the M shell, can hold a maximum of 18 electrons. The number of electrons that any particular element has in the third level depends on its location on the periodic table and can range from none to 18 electrons.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.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 >
