water, however, we are still unable to produce it at an affordable cost. The major problem is we are only able to produce hydrogen with a 70%-80% efficiency. This is due the complexity of water which, while ostensibly being a very simple molecule, is highly complex in the liquid state...
Atoms and ions consist of electrons that occupy orbitals somewhere around the nucleus of the atom. Orbitals are spaces around the nucleus that an electron has the greatest likelihood of occupying. Different orbitals have different energy levels and electrons will tend to occupy orbitals with the ...
