What Are Atoms Made Of?

Description

Everything is made up of atoms, but what are atoms made of? This program summarizes modern atomic theory and the chemistry of atoms. First, modern atomic theory is explained with emphasis on some of the major breakthroughs by Ernest Rutherford, who experimented with alpha particles; Niels Bohr, who observed the valency of elements; and Dmitri Mendeleev, who designed the periodic table of elements. Next, the structure of the periodic table is examined, including an explanation of its organization by atomic mass and reactivity. Then, valency and ways in which elements are combined to create different substances are illustrated. An informative and fast-paced survey of basic principles of chemistry.
