If mass is made of atoms with charges, why should gravity not come from them? All matter is built from atoms, and every atom contains charged components — positively charged nuclei and negatively charged electrons. While atoms appear neutral on the whole, the shielding is never perfect, and residual interactions remain. If every known force in nature arises from charges and their interactions, it is logical to ask why gravity should be the only exception. Instead of postulating an entirely new force or spacetime curvature, it is more natural to view gravity as emerging from the cumulative residual effect of these charges — a hidden electromagnetic phenomenon acting at the nuclear level.
Gravity is primarily a consequence of mass, not electric charge, although both are fundamental properties of matter. Here's why gravity doesn't directly "come from" the charges within atoms
Bittu Kumar "All matter is built from atoms" - not always. Neutron stars for example are composed of matter, but primarily not atoms, and they contain a much smaller component of charged particles than things made of atomic matter. Nevertheless, neutron stars have the gravity of a star and obey Einstein's theory of gravity. Mass determines gravity, not charge.
We also know that dark matter, whatever it is, is a major source of gravity (why we detected it in the first place), but does not interact with photons in the manner that electrons do, nor with magnetic fields. This sets an upper limit on its charge-to-mass ratio, which is absolutely tiny. So again, little or no charge, yet a high gravitational impact.
