Answer:
Bohr improved Rutherford's model by proposing that electrons travelled about the nucleus in orbits that had specific energy levels. They could jump from one level to another but could not be at any place in between, and they would absorb or emit specific amounts of energy (quanta) when they jumped between levels.

Answer:
Unfortunately, nobody reads Bohr nowadays so Bohr's arguments are not understood and transmitted. Modern quantum mechanics is more complete and superior as a physical theory to the old quantum mechanics, so the omission is perhaps understandable, but it is not forgivable.
Bohr's ideas explain the stability of H-atoms in a reasonable way, which is also correct in the modern theory. In modern quantum mechanics, it is obvious that there is a ground state for the electrons, because if you confine the electron to a box of radius a, it has a momentum of order 1a, and therefore a kinetic energy of 1a2, while the negative potential energy is only 1a, so there is a minimum distance,
