Explanation:
The equation is Fg = G(m₁m₂/d²).
G is the universal gravitational constant, but that isn't exactly a quantity.
m₁ and m₂ are the masses of the two objects, and those are quantities.
d is the distance between the two objects, and those are quantities.
So, masses and distance.
The structure of an atom is in the middle of an atom has the neutron (nucleus) which has no charge around the neutron is the protons which has a positive charge and the ones that orbit around the atom is the electrons which has a negative charge in it. The number of protons is call the Atomic Number. Protons have a relative charge of +1 and the electron have a relative charge of -1.
