The picture at "Atoms and Molecules" at: https://en.wikipedia.org/wiki/Electro, is wrong: the third row and the fifth row should be excluded because the table of the element's numbers go like:
2, 2, 6, 2, 6, 2, 10, 6, ...
and the f-level's row has 14 blocks.
This means the formulae is also not right: only a subset of the formulae get used.
Also to get the wave function of the second 6 and third 2 for example, we would need a sum of the given orbital wave functions.

The link only refers to a disambiguation page. Can you just insert the picture here?
You can use insert image icon after you press the preview button.

The picture is attached in .png format.

You refer to a table...

Yes, the Periodic Table of the Elements: this reflects electron orbitals in an atom.
-
I may be wrong: I considered them in the sequence they appeared in.

Anyway there is an error in the formula: r should be roh.

Using quantumn numbers n, l, ml and ms, we would expect:
2
2, 6
2, 6, 10
2, 6, 10, 14
2, 6, 10, 14, 18
etc.
But, because both n and l contribute to the energy of the electrons, it turns out that when placed in order of energy, it becomes:
2
2, 6
2, 6
2, 10, 6
2, 10, 6
2, 14, 10, 6
2, 14, 10, 6
2, 18, 14, 10, 6

But, because both n and l contribute to the energy of the electrons, it turns out that when placed in order of energy, it becomes:22, 62, 62, 10, 62, 10, 62, 14, 10, 62, 14, 10, 62, 18, 14, 10, 6
That is the order of the Periodic Table of the Elements. To be picky: mathematically there should be another row of "2" at the top.
-
Are the numbers in the picture in order: (n, l, m_l)?
-
(3, 0, 0), (2, 1, 0) and (2, 1, 1) should be grouped together as the 2p orbitals. I was wrong, the pictures are just not in the order of the Periodic Table of the Elements.
-
Anyway there is an error in the formula: r should be roh.
Do you mean rho (ρ) ?
-
Yes I meant rho (ρ).
No to my previous post, the 2p orbitals all have n = 3. In which case (2, 1, 0) and (2, 1, 1) must be superpositions of 2s and 2p or wrong?
