Question: If an electron has quantum numbers n=3, l=1, and m_l=-1, what is the possible value of the spin quantum number?

Options:

Correct Answer: +1/2

Solution:

The spin quantum number can be either +1/2 or -1/2, so both values are possible.

If an electron has quantum numbers n=3, l=1, and m_l=-1, what is the possible value of the spin quantum number?

If an electron has quantum numbers n=3, l=1, and m_l=-1, what is the possible value of the spin quantum number?

Step 1: Understand what quantum numbers are. Quantum numbers describe the properties of electrons in an atom.
Step 2: Identify the given quantum numbers: n=3, l=1, and m_l=-1.
Step 3: Recognize that the spin quantum number (s) describes the spin of the electron and can have two possible values.
Step 4: The possible values for the spin quantum number are +1/2 and -1/2.
Step 5: Since both values are allowed, conclude that the possible value of the spin quantum number is either +1/2 or -1/2.

Quantum Numbers – Quantum numbers describe the properties of electrons in an atom, including their energy level (n), angular momentum (l), magnetic orientation (m_l), and spin (s).
Spin Quantum Number – The spin quantum number indicates the intrinsic angular momentum of an electron, which can take values of +1/2 or -1/2.
