Abstract
It was not acceptable for me to use the values of gravitation constant and Coulomb's constant, which their values were derived in the 18th century by macroscopic methods, in the microscopic and subatomic scale. This was the idea that led to writing this article. Here we show that we are able to consider a large value for the gravitational constant, G, at the vicinity of matter (r<1Å). Today physics and chemistry need to this choice. By considering a large value for G, at the vicinity of matter, the stability of atom and atomic and molecular bonds can be explained by a different method. This article seems to pave the way to remove the strong interaction by gravitation force.
