Atomic Physics 1

shell

the collection of states with the same principal quantum number n (same energy)

subshell

the collection of states for which both the principal quantum number and azimuthal quantum number are the same

ionization energy

the energy required to remove the most loosely-bound electron from a neutral atom

electron affinity

the amount of energy released when an electron attaches to a neutral atom or molecule

atomic absorption/emission

an atom can transition from one energy state to another by emitting or absorbing light

electron orbital angular momentum

Planck’s constant(s)

electron orbital angular momentum (z-component)

Bohr magneton

orbital magnetic moment of electron

orbital magnetic moment of electron (z-component)

spin angular momentum of an electron

spin angular momentum of electron (z-component)

electron spin dipole moment

electron spin dipole moment (z-component)

semi-classical angle
