Every matter has a gravitational field. The gravitational field of the matter is a consolidation of the gravitational fields of all molecules or atoms of the matter. The envelope surfaces of electric fields of moving electrons in an atom or a molecule form the gravitational field of the atom or the molecule. This origin of the gravitational field is found in this article. A simplified macro model for an atom is also proposed for this purpose. As an application of the theory, a formula for finding velocity of electrons in an atom is derived.
