Atoms, once thought indivisible, are intricate worlds of smaller entities
Atoms, once thought indivisible, are intricate worlds of smaller entities. At their heart lies the nucleus, a dense core of protons and neutrons. Protons carry a positive charge and are made of three quarks; two up, one down; bound by the strong nuclear force. Neutrons, neutral in charge, also contain three quarks; one up, two down. These nucleons are held together by gluons, massless particles that weave the strong force like threads in a cosmic tapestry. Surrounding the nucleus, electrons orbit in quantized energy levels. Electrons are fundamental particles with negative charge and no known internal structure. Their behavior is governed by quantum mechanics, where position and momentum blur into probability. Beyond these, the quarks themselves come in six “flavors”: up, down, charm, strange, top, and bottom. They never exist alone, confined within larger particles. Gluons, the carriers of the strong force, constantly exchange between quarks, ensuring confinement. Other subatomic acto...
