Expert Answer:

Fire is not matter.It is energy. Fire is caused by the rapid oxidization of certain compounds. Since energy is not matter, it cannot be in a physical state. Though fire can be considered "fluid", it is not actually a liquid. It is energy (or the release of energy).

According to the Bohr's model, electrons can occupy only certain orbits, because they can radiate only certain quantities of energy.Hence , the cannot fall back to the nucleus as energy is Quantized.
