In most situations involving atoms and subatomic particles, the effects of gravity are extremely weak compared to other fundamental forces, such as electromagnetic forces. As a result, gravity is often considered negligible or insignificant when studying the behavior and interactions of electron particles within atoms.
The strength of the gravitational force is determined by the masses of the interacting objects and the distance between them. In the case of an electron, its mass is approximately 9.11 x 10^-31 kilograms, which is extremely small compared to the mass of larger objects like planets or stars. Additionally, the distance scale at which electrons interact within atoms is on the atomic or subatomic level, where gravitational forces are further diminished due to the relatively short distances involved.
In particle physics and quantum mechanics, which describe the behavior of subatomic particles, other forces and interactions, such as electromagnetic forces, strong nuclear forces, and weak nuclear forces, play a dominant role. These forces are much stronger than gravity at the subatomic scale and are essential for understanding the behavior of electrons within atoms.
However, it's important to note that gravity can become significant in certain extreme scenarios, such as in cosmology or in the study of objects with very large masses or energies, like black holes or neutron stars. In those cases, the effects of gravity cannot be ignored. But for most everyday atomic and subatomic interactions, gravity is considered to be negligible.
