[book] Gold (The Elements)— Sarah Angliss

Wars have been fought over it, currencies have been based on it, and sacred temples have been decorated with it. Gold, the brilliant metal that never loses its luster, is one of the world’s most valuable substances. Learn about the history of gold—from the early alchemists who tried to turn lead into gold to the modern particle accelerators that actually can turn atoms of lead into gold. The book discusses the chemistry of gold, where and how gold is found, the uses of gold alloys and films, how gold is worked with, and gold’s medical and scientific uses. Find out why gold is so valuable.

Power Words

chemical element A substance that contains only one type of atom and cannot be broken down into simpler substances. Ninety-two elements are known to exist naturally, and another twenty have been created by scientists. All the elements are arranged in the Periodic Table.

gold A shiny, yellow chemical element that is the most easily shaped of all metals. Gold is a good conductor of heat and electricity and does not rust easily. It is used to make jewelry.

malleable Capable of being shaped or formed, especially by pressure or hammering. Gold, silver, and copper are all malleable metals and are often shaped into coins or jewelry.

Periodic Table A table that arranges all the chemical elements in rows called periods, and columns called groups. Elements are placed in a particular period depending on the number of layers their electrons are in as they move around the nucleus. Elements are placed in a particular group depending on the number of electrons that are available to make bonds with other elements.
