What are the parts of an atom?
... What are the parts of an atom? As you have learned, an atom can be divided into smaller parts. That’s because atoms themselves are composed of particles even smaller then themselves. The parts are called protons, neutrons, and electrons. Protons and neutrons are found in the center of an atom, calle ...
