    Quantum mechanics didn’t supersede electromagnetism. Again, they’re different things. Electromagnetism is a fundamental interaction. Whereas quantum mechanics describes the mechanics of quantum particles. Whether those particles are affected by electromagnetic forces or not. It’s a description of how they behave at quantum scales.

    Coulomb’s law has nothing to do with quantum mechanics, it’s a description of how macroscopic charged particles interact. What the OP should have said to be correct is:

    Awesome to see the similarities between: Newton’s law of gravitation and Coulomb’s law

    I don’t know where he got quantum mechanics from.

    The relation between them is that they’re both forces that scale with the inverse square of the distance between the objects. Any force that scales with the inverse square of distance has pretty much the same general form.

    Another similarity is that both are incomplete, first approximations that describe their respective forces. The more complete versions are Maxwell’s laws for electromagnetism and General Relativity for gravity.

    The original spelling wasn’t aluminum, it was alumium. Which then was proposed to be aluminium in French, and got picked up by the Royal Society. After, the guy who introduced the term to the Royal Society (Humphry Davy) started calling it aluminum but the other term had already stuck.
