Quais são os símbolos dos quatro números quânticos usados na especificação de elétrons em átomos?

Question:

What are the symbols of the four quantum numbers used in the specification of electrons in atoms?

Answer:

The four Quantum Numbers along with Symbol and brief explanation are as follow,

1) Principal Quantum Number:

Symbol = n

This quantum number explains the main energy level or main shell in which an electron is present.

2) Azimuthal Quantum Number:

Symbol = l

This quantum number is associated with principal quantum number and it represents the sub energy levels or sub shells.

3) Magnetic Quantum Number:

Symbol = m

This quantum number explains the magnetic properties of an atom. Electrons with different magnetic quantum numbers have different orientations in applied magnetic field.

4) Spin Quantum Number:

Symbol = s

This quantum number explain the spin of an electron about its axis. The spin may be clockwise or anti-clockwise.
