Carbon is an atom with 12 nucleons, or 6 protons and 6 neutrons. It is necessary for all carbon based life forms. It has a sparse electron cloud around it. It is in the microscopic level of a Green Planet.
The microscopic level of Green Planet .
The electron cloud is the size of a bacterium, which would not be possible in real life because billions of atoms are needed to make bacteria, not just one. In addition, the nucleus of the atom should be 100,000 times smaller than the electron cloud. All this results in the atom having a nucleus size of 35 nanometers, millions of times larger than what it should be.
