9. Elements can gain the stable atomic structure of a noble gas by either gaining or losing electrons. Two examples are sodium, which, when it loses an electron, has the same atomic structure as neon, a noble gas; and chlorine, which when it gains an electron, has the same atomic structure as argon, another noble gas.

Atoms are composed of three kinds of particles – electrons, protons, and neutrons. Protons have a positive charge and a mass of 1 atomic mass unit (amu). Neutrons have no charge (they are neutral) and have a mass of 1 atomic mass unit. Electrons have a negative charge and have a mass of 1/1840 that of a neutron or proton.
