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.
Learn MoreThe 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.
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 >For hydrogen, an electron jump from the second energy level down to the first emits a photon within the ultraviolet range of the spectrum at a wavelength of 1.21 x 10^{-7} meters, or 121 nanometers. The emitted photon has exactly 10.2 electron volts of energy.
