1λ=R(1n2f−1n2i)

Rydberg constant

1.097×107m−1

3

Bohr radius

the mean radius of the orbit of an electron around the nucleus of a hydrogen atom in its ground state

4

energies of hydrogenlike atoms

En=−Z2n2E0(n=1, 2, 3,…)

5

orbital magnetic field

the magnetic field generated due to the orbital motion of electrons

6

angular momentum quantum number

a quantum number associated with the angular momentum of electrons

7

spin quantum number the quantum number that parameterizes the intrinsic angular momentum (or spin angular momentum, or simply spin) of a given particle Pauli exclusion a principle that states that no two principle electrons can have the same set of quantum numbers; that is, no two electrons can be in the same state gamma rays one of the types of rays emitted from the nucleus of an atom
