Bohr's theory of the hydrogen atom assumed that...

1. the electron in a hydrogen atom can jump from one energy level to another without gain or loss of energy.
2. electromagnetic radiation is given off when electrons move in an orbits around the nucleus.
3. because a hydrogen atom has only one electron, the emission spectrum of hydrogen should consist of only one line.
4. the electron can exist in any one of a set of discrete states (energy levels) and can move from one to another by emitting or absorbing radiation.
5. energy, in the form of radiation, must be continually supplied to keep an electron moving in its orbit.
