What does it mean that the Bible was divinely inspired? Some of the symbols used for elements that have been known since antiquity are derived from historical names that are no longer in use; only the symbols remain to indicate their origin. Electrons orbit the nucleus of the atom at great distance and velocity. The mass of a proton or a neutron is about 1836 times greater than the mass of an electron. Even though the mass of the electron is infinitesimally smaller than that of the proton, the net negative electrical charge of an electron is proportional to the net positive charge of the proton. The four elements common to all living organisms are oxygen (O), carbon (C), hydrogen (H), and nitrogen (N), which together make up about 96% of the human body. The rest masses of quarks contribute only about 1% of a protons mass. Figure 2.1.1: The structure of the nuclear atom with a central nucleus and surrounding electrons.
