Molecular hydrogen gas (h2) is diamagnetic. a. what does this suggest about the spins of the two electrons in the hydrogen molecule? explain why. (remember that the electron magnetic moment is 658 times that of the proton.) b. what would you expect the magnetic behavior of atomic hydrogen gas (h) to be? justify your answer.
