This song explains how electrons are ordered in principal energy levels, sublevels and orbitals and how to fill in the electrons in an electron configuration. Music and lyrics copyright 2007 by Mark Rosengarten. All rights reserved.

Lyrics:

The first energy level is really small
It hardly has room for electrons at all
An s sublevel is all there is
With 2 electrons that constantly whiz

1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3-d-10!

A little bit larger, the second shell
Two sublevels therein do dwell
An s sublevel that maxes at two
And six for a p, if thats OK with you!

1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3-d-10!

The third shell is even larger still
An s and a p top the bill
A d sublevel is added on top
10 electrons can fit at a pop!

1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3-d-10!

The fourth shell is the largest yet
An s and a p and a d, I bet
An f sublevel is also seen
How many electrons? Up to fourteen!

1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3-d-10!

1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3-d-10!

Why does 4s fill up before 3d?
Because the 4th shells enormous, you see
Overlap 4s has less energy
Than the supposedly lower 3d!

1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3-d-10!

The overlaps increase in frequency
4f fills up way after 5p
Keep track of the overlaps, really cool
You gotta use the diagonal rule!

1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3-d-10!

I cant wait, just tell me when
Count em all up, and lets start again!
One sublevel fills and the next can start
Electron config is something that I heart!

1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3-d-10!
