2020-08-16 · Atom - Atom - Bohr’s shell model: In 1913 Bohr proposed his quantized shell model of the atom (see Bohr atomic model) to explain how electrons can have stable orbits around the nucleus. The motion of the electrons in the Rutherford model was unstable because, according to classical mechanics and electromagnetic theory, any charged particle moving on a curved path emits electromagnetic

The attempts to calculate the spectrum of helium from the wave equa- tion of mechanics have Application to Helium.-The wave equation for the helium atom is. The electron energy levels for a helium atom demonstrate a number of features of as would be expected by modeling it after the hydrogen energy levels. Neils Bohr's model of the atom provided a wonderfully accurate explanation of the spectrum of hydrogen, but when it was applied to the spectrum of helium it  Lecture 22: Helium Atom‡ to discuss the next-simplest system: the Helium atom.
