- An atom is the basic unit that makes up all matter. There are many different types of atoms, each with its own name, mass and size. These different atoms are called chemical elements. The chemical elements are organized on the periodic table. Examples of elements are hydrogen and gold. Atoms are very small, but the exact size changes depending on the element. Atoms range from 0.1 to 0.5 nanometers in width. One nanometer is about  100,000 times smaller than the width of a human hair.

What does an atomic number represent? The atomic number represents or stands for the distinct identity of a chemical element. It is usually defined as the number or protons present in an atom of an element, which is also equal to the number of electrons.

What is Atomic Theory? Atomic theory is the idea that matter is made up of little units called atoms. When the ancient Greek philosopher Democritus came up with the idea in the 5th century BC, is was originally meant to refer to indivisible units. As of 1897, the British scientist J.J. Thomson discovered that atoms are in fact made up of smaller particles.

What is Atomic Mass? - Definition & Examples Atomic mass is typically calculated by adding the number of protons and neutrons together, ignoring the electrons because of their small size. Daltons are the standard units used for measuring atomic mass. Atomic mass units, or amu, are also used to measure atomic masses, and they are equal to daltons. The atomic mass of an atom will change depending on its amount of protons and neutrons and will be different for each individual element.

Cicero, Illinois Originally, Cicero Township occupied six times its current territory. Weak political leadership and town services resulted in cities such as Oak Park and Berwyn voting to split off from Cicero, and other portions such as Austin were annexed into the city of Chicago.

What is the Difference Between an Atom and an Ion? An atom is the smallest possible unit of an element. Atoms are considered to be the basic building blocks of matter because they cannot be divided into smaller particles by any chemical process. An atom consists of three types of subatomic particles: neutrons, protons, and electrons.
