For a d orbital, what is a possible value of the angular momentum quantum number, l?

• A. 2
• B. 1
• C. 3
• D. 0

Answer: (A)

Verified step by step guidance

1. Recall that the angular momentum quantum number \(l\) defines the shape of the orbital and can take integer values from \$0\( up to \)n-1\(, where \)n$ is the principal quantum number.
2. Each value of \(l\) corresponds to a specific type of orbital: \(l=0\) is an s orbital, \(l=1\) is a p orbital, \(l=2\) is a d orbital, and \(l=3\) is an f orbital.
3. Since the problem asks for the angular momentum quantum number for a d orbital, identify the value of \(l\) associated with d orbitals.
4. Match the letter designation 'd' to its corresponding \(l\) value, which is \$2$.
5. Therefore, the possible value of the angular momentum quantum number \(l\) for a d orbital is \$2$.
