Molecular formula :
nature : in quantum mechanics, the state-level and the two terms have different meanings. State wave function is expressed in each of the different wave function is a different state. Energy is used to set the value of energy expressed in each of the energy value is a different level. If a level with more of the state should be relative, as Jane and energy, the same level of the number of different states as the degeneracy of the level and degree. In hydrogen atoms, each level is under n2 independent state, and that the degree of SR n2. For example : n = 2, ψ 2s, ψ 2px, ψ 2py and ψ 2pz a total of four independent state, and the degree of SR 4.
