Each atomic orbital has designated shapes that are determined by the angular momentum quantum number (l)

Atomic Orbital Shape

Concept #1: Quantum Numbers and Atomic Orbital Shape

Transcript

In this new video, we're going to continue with atomic shape. Remember, we said that the second quantum number, which is known as our angular momentum quantum number, tells us the shape of a particular orbital. Each one has a specific shape associated with it. Remember we can also call this our azimuthal or subsidiary quantum number. All three terms mean the same thing.
Now, we're going to say it uses the variable l and the formula n minus one. We're going to say each sublevel has its own l value associated with it. If we know the sublevel or sub-shell letter, then we know what the l value is. S is zero, p is one, d is two, f is three, g is four, h is five. 

Example #1: Based on the following atomic orbital shape, which of the following set of quantum numbers is correct: 

a) n = 8, l = 1, ml = 1/2

b) n = 8, l = 2, ml = -2

c) n = 8, l = 0, ml =  1

d) n = 8, l = 0, ml = 0

Practice: Based on the following atomic orbital shape, which of the following set of quantum numbers is correct:

a) n = 2, l = 1, ml = +1, ms = -1

b) n = 4, l = 1, ml = -2, ms = +1/2

c) n = 3, l = 1, ml = -1, ms = 0

d) n = 2, l = 1, ml = +1, ms = -1/2
