Question: Which of the following sets of quantum numbers corresponds to an electron in a 4d orbital?

Options:

Correct Answer: n=4, l=2, m_l=1

Solution:

For a 4d orbital, n=4 and l=2. The m_l value can be -2, -1, 0, +1, +2.

Which of the following sets of quantum numbers corresponds to an electron in a 4d orbital?

Which of the following sets of quantum numbers corresponds to an electron in a 4d orbital?

Step 1: Understand what quantum numbers are. They describe the properties of electrons in atoms.
Step 2: Identify the principal quantum number (n). For a 4d orbital, n is 4.
Step 3: Identify the azimuthal quantum number (l). For a d orbital, l is always 2.
Step 4: Determine the magnetic quantum number (m_l). For l=2, m_l can be -2, -1, 0, +1, or +2.
Step 5: Combine the values: For a 4d orbital, the quantum numbers are n=4, l=2, and m_l can be -2, -1, 0, +1, or +2.
