the diagram shows the different models of the atom that eventually led to the modern atomic theory. which model was proposed as a result of Rutherford scattering experiment where positive particles did not pass straight through a foil as expected

Acompound has a molecular weight of 12.124 atomic mass units and the empirical formula c3h40. what is the molecular formula of the compound?

I'm learning about the periodic tables and what each subject's configuration is. for example, hydrogen is 1s^1, but i don't understand how you get that. can someone me understand how to figure out how to figure this out? sorry if the question makes no sense, but it would really a lot if you could me understand! you so much if you can!
