\(q_e=\cfrac{1}{9.029022e26}=1.107540e-27=m_e\)
is also the elementary gravitational mass, \(m_e\).
\(m_e*77=\cfrac{1}{9.029022e26}*77=8.5281e-26\)
and with the maximum attractive force, considering shielding,
\(\left\lfloor\cfrac{77}{2}\right\rfloor=\left\lfloor38.5\right\rfloor=39\)
\(m_e*39=\cfrac{1}{9.029022e26}*39=4.3194e-26\)
We could be talking about the atomic mass constant or the neutron rest mass. A proton as an elementary charge particle does not experience a force in a gravitational field and have no gravitational mass. But it has inertia under an electric field.
