Atoms are the tiniest particles of any element
Nucleus(positive charge)
Electrons(negative charge)
Electrons orbit the nucleus of an atom
Each orbit can hold a specific number of electrons
Atoms prefer filled orbits to balanced charges
So…
Rubbing different materials together helps electrons move from one material to the other, which puts a positive charge on one and a negative charge on the other.
Unlike charges attract each other
Like charges repel each other
