Definition & Meaning
Isotopes, ions, and atoms are fundamental concepts in chemistry and physics. An atom is the basic unit of matter, consisting of a nucleus surrounded by electrons. The nucleus contains protons and neutrons. Protons are positively charged, while neutrons have no charge. Electrons, which are negatively charged, orbit the nucleus in various energy levels.
An isotope refers to variants of a particular chemical element that have the same number of protons but different numbers of neutrons. This difference in neutrons results in varying atomic masses. For example, carbon-12 and carbon-14 are isotopes of carbon, with twelve and fourteen nucleons, respectively.
An ion is an atom or molecule that has gained or lost one or more electrons, resulting in a net electric charge. If an atom loses electrons, it becomes a positively charged ion, known as a cation. Conversely, if it gains electrons, it becomes a negatively charged ion, called an anion. Sodium (Na) becomes a sodium ion (Na+) when it loses an electron, while chlorine (Cl) becomes a chloride ion (Cl-) when it gains an electron.
