Lithium contains three electrons and therefore has a completely filled 1s orbital and one more electron in the next higher 2s orbital. The electronic configuration is therefore 1s 2 2s 1 or [He]2s 1, where [He] refers to the electronic configuration of helium. Beryllium has four electrons, two in the 1s orbital and two in the 2s orbital. The electron in a Hydrogen atom can only have certain energies. These energies are called the Hydrogen's “energy levels”. The different energy levels of Hydrogen are denoted by the quantum number n where n varies from 1 for the ground state (the lowest energy level) to ∞, corresponding to unbound electrons.

    If the electron spins clockwise on its axis, it is described as spin-up; counterclockwise is spin-down. This is a convenient explanation, if not fully justifiable mathematically. The spin angular momentum associated with electron spin is independent of orbital angular momentum, which is associated with the electron's journey around the nucleus.

One of the first steps toward the resolution of such issues was provided by the French physicist Louie de Broglie.Bohr model describes the atom as a positively charged nucleus, which is surrounded by electrons. Electrons travel in circular orbits, attraction is provided by electrostatic forces. Normally occupied energy level of the electron is called the ground state. The electron can move to the less – stable level by absorbing energy. If the electron spins clockwise on its axis, it is described as spin-up; counterclockwise is spin-down. This is a convenient explanation, if not fully justifiable mathematically. The spin angular momentum associated with electron spin is independent of orbital angular momentum, which is associated with the electron's journey around the nucleus.
