because only one of these would have a minimum energy

because only one of these would have a minimum energy

angular momentum must be in the direction of spin of electron

because electrons go arround only in horizontal obits.

the electron would not move in circular orbits

the energy would be (2)⁴ times that of a H-atom

the electrons, orbit would go around the protons

the molecule will soon decay in a proton and a H-atom.

because of energy conservation

without simultaneously releasing energy in the form of radiation

because of momentum conservation

because of angular momentum conservation.

will not be applicable to hydrogen in the molecular form 

will not be applicable as it is for a He-atom

is valid only at room temperature

predicts continuous as well as discrete spectral lines

if we measure the frequencies of light emitted when an excited atom falls to the ground state

if we measure the frequencies of light emitted due to transitions between excited states and the first excited state

in any transition in a H-atom

as a sequence of frequencies with the higher frequencies getting closely packed.
