I observed that there were no daily challenge on community for a while. So here it is.
If you were/are a science student you might know about Electronic Configuration
(Electron configuration - Wikipedia). Challenge
Create a program that inputs the atomic number and gives the electronic configuration for that atomic number. You may consider adding logic for Afbau Principle . It will make it a lot more challenging.
I think you Forget about the Assumptions in Chemistry they say Only 8 elections can Be added to one electronic and been added to 1 Octave but in some case there are more than eight electrons in 1 Octave.
Maybe adding List For All of this element’s will be Headache. I will recommend to go with api if any.
