The atomic size of an atom, also called the atomic radius, refers to the distance between an atom's nucleus and its valence electrons. Remember, the closer an electron is to the nucleus, the lower its energy and the more tightly it is held. Moving Across a Period Moving from left to right across a period, the atomic radius decreases.

Thomson analyzes the evolution of modern ideas on the inner workings of atoms and J.J. Thomson’s contributions. This lesson investigates the development of modern atomic theory.
People have long speculated about the structure of matter and the existence of atoms. The earliest significant ideas to survive are due to the ancient Greeks in the fifth century BCE, especially those of the philosophers Leucippus and Democritus.
This tutorial: A Brief History of Rutherford's Experiment starts the story. Interest in the Thomson Model fell off rapidly after 1911, although in 1914 and 1915 attempts were made to resurrect it. These efforts came to nothing and the Thomson Model assumed its place in history as the first modern attempt to construct a theory of atomic structure.
