If you were to separate all of the electrons and protons in 1 g (0.001 kg) of matter, you’d have about 96,000 C of positive charge and the same amount of negative charge. If you placed these charges 5 m apart, how strong would the attractive forces between them be?

1. F = k Q^2/R^2

k is the Coulomb coefficient. Look it up.
Q = 96000 C
R = 5.0 m

The answer will be in newtons.

How does the structure if an atom relate to how electric charges form? I don't quite understand the question. All electrons and protons have charges. The charges do not "form", they are already there. They are part of every atom.
