I've been reading of the Bohr model lately and I was wondering...do we only know the energy levels of electrons orbiting hydrogen or do we know these levels for other atoms? If not, is there a way to calculate this using the Shrodinger or is this just part of the whole mystery?
Thank you for...
it's like, with every action there's some reaction or something opposite , the universe is expanding, it's infinite, and it's like contracting too, infinitely, so it's like a heavy load inward , just as much outward
