How many orbitals are there in the n = 4 level of the h-atom?

Chemistry
1 answer:
Nikolay [14]3 years ago
8 0

The H-atom has fourth energy level with n=4.

This energy level can have values of orbital angular momentum l = 0, 1, 2, 3

Now each l can also have magnetic momentum ml from – l to l.

Therefore,

l = 0

<span>ml = 0 </span>

l = 1

ml = -1, 0, 1

l = 2

ml = -2, -1, 0, 1, 2

l = 3

ml = -3, -2, -1, 0, 1, 2, 3

Now adding up all the number of ml’s will give us the total number of orbitals:

orbitals = 1 + 3 + 5 + 7

orbitals = 16

 

Alternatively, we can simply use the formula:

<span>orbitals = n^2 = 4^2 = 16</span>
