Does Gravity operate Orbit of the Electrons nearby the Nucleus?

From the study of physical Chemistry (which includes measure Mechanics) we know that the buildings of matter and the periodic table that results is a consequence of the only the electromagnetic force and nothing else, unless gravity is very strong-so strong that it dominates other forces. Such conditions do not exist on Earth.

Of course gravity pulls atoms down to Earth, but it does not work on the electronic structure...However the inquire does not ask about the pull of gravity on particles, but rather about the orbits of electrons colse to an atom, and if gravity plays a role.

Nuclear Reactor

Let us consider one H atom. The mass of a proton is 1.67262158 × 10-27 kilograms and the electron rest mass is 1800 times lighter 9.10938188 × 10-31 kilograms. The Coulomb entertaining force in the middle of these two charged particles is many orders of magnitude larger than gravity in the middle of them.

More specifically we can compare the gravitational attraction in the middle of an electron and a proton, to that of their electrostatic attraction. Using Newton's Law and Coulomb's law and plugging in the underlying electron charge, and for gravity, the above masses, and known constants, shows that the Coulomb force is a whopping 1040 times stronger than gravity in the Hydrogen atom.

That is 10,000,000,000,000,000,000,000,000,000,0... (40 zeros) times stronger!!!

Electronic buildings of Matter

Understanding of physical Chemistry also explains that electronic buildings of matter is governed solely by Coulomb's law: the attraction and repulsion in the middle of charged particles: But read on.

We only know of four forces: gravity (range: infinite), electromagnetic (range infinite), weak nuclear force (leads to beta decay) (range only within a nucleus); the strong nuclear force (range only within a nucleus). That's it folks.

The nuclear troops are much stronger than the electromagnetic force over the same distance. The vigor released in nuclear reactors is many orders of magnitude greater than chemical vigor because E=mc2.

Gravity and Black Holes

Having said all that, I want to think a bit more about the inquire covering the box. What is a neutron star? a black hole? A neutron star has a mass so great that it overcomes the electromagnetic force and pushes the electrons down onto the nucleus.

Proton+ + Electron- ->Neutron

I have put a plus payment on the proton and a minus payment on the electron to emphasize that they repel each other. So to push an electron out of its orbit and down to the covering of the proton must overcome the electrostatic repulsion in the middle of them.

The gravitational field needed to do this is more than 1040 times stronger than on Earth!! That star is basically made up of neutrons. Recall that Ernest Rutherford found that an atom has a very dense nucleus. Fantasize the gravitational field of a star made up of nuclei rather than atoms! Under such strong gravitational fields, the electronic buildings does depend upon gravity.

Same for black holes. Gravity is so strong that nothing can escape it, and it appears to dominate all other forces.

Finally, physicists seek a unified theory to recite the mechanics of all forces. Of the four forces, three have been unified (using measure mechanics (quantum field theory really)). Only gravity is not understood.
