Atoms are probably one of the smallest existing things. Even on just a little fingernail it would take 100 milion atoms. It would take up to many atoms to name to be in an average humans body. The parts of an atom are proton neutrons and electrons . Protons have a posative charge, neutrons are not charnged, and electrons have a negative charge.
the way to tell that its a posative charge is if there are more protons than electrons. The way to tell if it is a negitive charge is if there are more electrons than protons . And finnaly to tell if there is a netral charge there has to be the same number of electrons and protons.
