The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume). Chemical properties. Atoms of the same element that differ in atomic mass are called isotopes.

Electrostatic Force. An interesting characteristic of the electrostatic force is that it can be either attractive or repulsive, unlike the gravitational force which is only ever attractive. The relative charges on the two objects is what determines whether the force between the charged objects is attractive or repulsive.

I’ll just calculate the total force as either the upward pushing force plus gravity while "in contact" with the ground or just gravity after that. It should be a fairly straightforward numerical.
