Definitions for "Atoms"
One of the tiny particles of which all things are made. Each atom is made up of protons and neutrons in a nucleus, and electrons which revolve around the nucleus. Every substance has its own kind of atom. Atomic energy is the energy that is released when atoms are forced to join together or to split apart.
Small particles that make up matter. Atoms are comprised of neutrons, protons, and electrons. Protons have a positive charge, electrons have a negative charge and neutrons are neutral in their charge.
All elements are made of atoms. An atom consists of a nucleus containing protons and neutrons, surrounded by electrons. The periodic table

Atoms are basic Yacas objects that are used to represent symbols, numbers, and function names. An atom has a string representation which is shown when it is displayed. For example, 3.14159, , A123, +, "good morning" are atoms. Atoms can be of type string, number, or symbol. For example, y1 is a symbolic atom, 954 is a number atom, and "" is an (empty) string atom. Symbolic atoms are normally used in Yacas to denote mathematical unknowns and function names. Number and string atoms are used to denote values. A symbolic atom can be bound to a value (in which case it becomes a variable), or to a rule or several rules (in which case it becomes a function). An atom can also have a property object.
