"If you've ever played with building blocks, you know a bit about how atoms work already. They're the building blocks of nature. In fact, everything in nature is made up of the super-small particles called atoms. This accessible book is an inviting look at the basic units of all matter. Young scientists will discover how atoms combine to form elements and how they're used to produce energy. Fascinating fact boxes and helpful diagrams take the mystery...

In this video segment, watch former astrophysicist Dr. Graham Phillips travel to Switzerland to check out the most powerful atom smasher in the world. It's about to tackle some of the most colossal questions about some of the smallest particles in our universe. Fourteen billion years later, scientists will be able to recreate the earliest moments of the Big Bang, deep underground in a 27-kilometer-long tunnel beneath the Swiss-France border. It might...

Description
This film presents the birth of an atom and its structure, featuring the following scientists who aided in the discovery: Albert Einstein; John Dalton; Joseph John Thomson; Ernest Rutherford; Max Planck; Niels Bohr. Throughout the film, animations of concepts in theoretical physics allow viewers access into the minds of geniuses.
17) Atoms and Light
Language
English
Description
Identification of electrons, protons, and neutrons led to a modern subatomic theory. The study of atomic spectra-the light given off by atoms at definite wavelengths-led to the Bohr atomic model, where electrons at distinct energy levels move between these levels by absorbing and emitting discrete quanta of energy. The measurement of atomic spectra has applications in astrophysics as well as forensic chemistry.

Description
For centuries, chemists tried to organize elements around patterns of chemical and physical trends. Physical characteristics, including atomic radius and reactivity, depend on electron configuration and can be teased from a careful understanding of the periodic table. Today the periodic table is continually updated as new heavy elements are synthesized in research laboratories.
