What are the four quantum numbers and the properties to which they refer?

Answer 1

#n, l, m_l,# and #m_s#; details below.

#n#: the principal quantum number relates the size of the electron orbital #l#: the angular quantum number relates shape of the electron orbital #m_l#: the magnetic quantum number relates the spatial orientation of the electron orbital #m_s#: the magnetic spin quantum number relates the rotational direction of each electron within an orbital (at most two at a time in accordance with the Pauli exclusion principle)

The electron's primary energy level is denoted by its Principal Quantum Number (n). Its orbital shape is indicated by the Angular Momentum Quantum Number (l). An orbital's orientation in space is specified by the Magnetic Quantum Number (m). The spin direction of an electron within an orbital is described by its Spin Quantum Number (s).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
