The greater the orbit of an electron around its proton at the nucleus of an atom, the more Nuclear Mass the atom attains.
Atomic mass is the weight of a combination of single (hydrogen) atoms collectively called an element. It determines the density of matter by volume.
Nuclear Mass is relative to the ‘space’ between the electron and the nucleus within an atom. It determines the density of latent potential energy by volume.
The closer the electron is to the proton, the less massive is the atom and the less nuclear mass it has.
Nuclear Mass is the measure of the magnitude of energy within matter.
The magnitude of matter is the measure of the latent energy within matter, which is relative to the space within matter.
Space = energy =power.
The nuclear mass of matter is relative to the magnitude of its latent energy.
Matter is formed by the separation of the electron and the proton from the neutron.
The more separation between the electron and the neutron, the more material it becomes, the more massive it becomes and the more nuclear mass it has.
The more nuclear mass it has the greater the potential energy it achieves and the greater the force of attraction it has to manifest into form.
As Energy expands its Motion, Matter contracts and becomes massive.
