Letter Names

Postby Jada Brown 2H » Sat Oct 19, 2019 9:31 pm

Does anyone know if there is a significance to the use of the specific s, p, d and f letters for the shells? If so, what is that significance?

The letters themselves represent a word. S represents sharp, p represents principal, f represents fundamental and d represents diffuse.Thi sis from the spectra of the alkali metals.

We use spdf in order to make up their orbital configurations.

After doing a little online research, the s, p, d, and f letters do have a history that can be discovered through this link: https://pubs.acs.org/doi/pdf/10.1021/ed084p757

That's interesting to learn! Honestly, I've been looking at the letters for so long but haven't really considered what they stood for! I originally thought s meant spherical, haha; but it's really cool to look at the origins of the letters that we've all been writing over and over again. Thanks for sharing!
