Introduction and aims. The development of Quantum theory in the early 20. th. century drastically changed our views on the nature of light, allowing us to consider it as a particle as well as a wave. . Review & Introduction for Science 10. Vocabulary. ATOM. :. smallest particle of an element, has a neutral charge.. ELEMENT. :. made up of 1 type of atom (. eg. . Oxygen, . O. ). COMPOUND:. . a pure substance made up of 2 or more elements that are . Energy that travels as a wave through space. Wavelength –. λ – distance between corresponding points on adjacent waves. Frequency – f – waves per second. Spectrum. Breakdown of electromagnetic radiation by increasing wavelength. Chapter Big Idea . The atoms of each element have a unique arrangement of electrons..
