Electrons should move around the nucleus but only in prescribed orbits. When jumping from one orbit to another with lower energy, a light quantum is emitted. Bohr's theory could explain why atoms emitted light in fixed wavelengths. akstotz https://padlet.com/akstotz/tin732k2vf85/wish/149887510 2017-01-27 14:42:44 UTC https://padlet.com/akstotz/tin732k2vf85/wish/149887510 Martin Karplus akstotz https://padlet.com/akstotz/tin732k2vf85/wish/149887511 - made Newton’s classical physics work side-by-side with quantum mechanics.
