Calculating quantum numbers

[Drew Myers 4G]

What is the best way to calculate quantum numbers?

[Jesalynne 2F]

If you're asked to give the quantum numbers for an atom or an ion you can write out the electron configuration of it and from there you can easily find out the quantum numbers.

Writing out the electron configuration will give all 4 quantum numbers in some respect

[Sidharth D 1E]

Identifying the subshell in which the electron exists in will give you the first two quantum numbers, and the orbital will give m_l and the spin of the electron will tell you if it is +1/2 or -1/2.

Focus on the last electron when calculating quantum numbers. N and L can be calculated by simply looking at the primary quantum number and the angular orbital number. Ml and Ms will tell you the spin and specific orbital of that electron.
