Bohr suggested the revolutionary idea that electrons "jump" between energy levels (orbits) in a quantum fashion, that is, without ever existing in an in-between state. Thus when an atom absorbs or ...

The typical size of atoms and small molecules is around 1 × 10-10 m (0.1 nm). For example: diameter of a hydrogen atom, H 1.0 × 10-10 m width of a hydrogen molecule, H 2 2.9 × 10-10 m ...

One is the spectroscopy of the internal structure, the internal energy levels of the anti-hydrogen atom to compare them ... "Hydrogen has quantum levels, principal quantum levels (i.e., n=1 ...

We've mentioned fuel cell manufacturer Quantum a few times recently in conjunction with their hydrogen storage systems being selected by General Motors for the fleet of fuel cell powered Equinoxes ...

For example, the electron in a hydrogen atom attracts the proton that ... "Two-loops" refers to the Feynman diagrams that describe this quantum process—two virtual photons from the quantum ...
