I How do I make an atomic oscillation?

    How do I make an atom oscillation?
    What is the thermal energy that an atom emits?

    Shake it.

    You can make an atom oscillate by shaking it.

    None. Single atoms don't emit thermal energy. At least I wouldn't call it thermal energy. The radiation emitted from a single atom is caused by electronic transitions (electrons moving between various energy levels in their orbitals) and the spectrum is one of discrete frequencies, not a continuous spectrum like you see in bulk materials. For example, a hydrogen atom can emit radiation at 4 distinct frequencies in the visible part of the spectrum, whereas the spectrum of a hot object composed of trillions of atoms is continuous from red to violet (and beyond both ends).

    Even spectra of big collection of atoms cant be continuous but frequencies might be close enough to give a look of continuity.

    Hmm. Maybe. But I'm not so sure. Electronic transitions are not the only way that light can be generated from atoms within a bulk material, and I don't know if they other ways (acceleration of moving charges, discrete transitions being red/blue shifted from their motions, etc) can generate a continuous spectrum or not.

    you can't
    A single atom, neutral, there is really no way I know (I could be mistaken) to make it oscillate.
    Bind two or more atoms together, make a molecule and then, you have vibrational and rotational energy levels.

    I don't see how the LHC would have anything to do with this thread.
    You can put an ion in an oscillating electric field to make it oscillate. You can put a neutral atom in a suitable magnetic trap and make it oscillate. And various more methods.
