Question

Use the relative size of the 3s orbital represented below to answer the following questions about Orbitals A-D. Which orbital has the highest value of n ? A C D Which orbital(s) have a value of l =1? A Which orbital(s) have a value of l =2? A In an atom, how many other orbitals will have both a value of n and a shape identical to Orbital B? (Use Orbital B as a reference and do not include it in your count.) 1 2 3 4 In an atom, how many other orbitals will have both a value of n and a shape identical to Orbital C? (Use Orbital C as a reference and do not include it in your count.) 1 2 3 4 Which orbital has the highest energy? A

Explanation / Answer

Here A is a 3P orbital, B is a 3d orbital, C is a 2P orbital and D is a 4dz orbital.

(a): D has the highest value of n(n=4).

(b): For P orbital, l = 1. Hence A and C have l = 1.

(c): For d orbital l = 2. Hence B and D have l = 2.

(d): Orbital B is a 3dxy orbital. Hence 3dyz and 3dzx will also have same 'n' value and same shape. Hence the answer is 2.

(e): Orbital C is a 2Px orbital. Hence 2Py and 2Pz will also have same 'n' value and same shape. Hence the answer is 2.

(f): D orbital has the highest energy
