Some people who try to deny the Cavendish Experiment say that the masses attract each other because of the atoms, not gravity. Doesn't an atom have a null electric field by nature? Is there any other way they could attract each other?

To a high degree of precision, an atom is electrically neutral at macroscopic distances. This means that the atoms in the cavendish weights are incapable of exerting electrostatic forces on one another in the cavendish experiments- unless they are not electrically shorted to each other and tied to earth ground, as the experiment requires.
Fans of crank physics wouldn't be fans at all if they actually took the time and had the ability to understand the topic. They usually get in trouble with the math and for that reason find it easier to latch onto one crackpot fantasy or another that, being fantasies, contain no math.
And, being crackpots themselves, it is impossible to convince them of the truth. As such, attempting to reason with them is a complete waste of time.
