Atomic Structure An atom is a complex arrangement of negatively charged electrons arranged in defined shells about a positively charged nucleus. This nucleus contains most of the atom's mass and is composed of protons and neutrons (except for common hydrogen which has only one proton). All atoms are roughly the same size Protons Positively charged particles found within atomic nuclei Neutrons A subatomic particle of about the same mass as a proton but without an electric charge, present i...
