List the quantum numbers associated with all of the 5d orbitals
Whitepunk [10]

Answer:

Here's what I get  

Explanation:

If the orbital is 5d, n = 5 and l=2.

mₗ = -l, -l + 1, -l + 2,  …., l

(mₛ is a quantum number for electrons)

Thus, we can have the following combinations.

\begin{array}{ccr}\mathbf{n} & \mathbf{l} & \mathbf{m_{l}}\\5 & 2 & -2\\5 & 2 & -1\\5 & 2 & 0\\5 & 2 & 1\\5 & 2 & 2\\\end{array}

That makes a total of five 5d orbitals.

The pictures below show what two of them look like.
