Gold is a chemical element. Its symbol on the periodic table is Au, and it is classified as a transition metal. It has an atomic number of 79, which is one of the higher atomic numbers of elements that occur naturally.
Elemental gold is not flammable. Flammability requires elements to be able to unite with oxygen in a combustion reaction. The inert electronic configuration of gold makes it unreactive with oxygen even in molten form.
The English word "gold" comes from an Anglo-Saxon word "gohl," thought to mean "yellow, green or shiny." The chemical symbol for gold is Au, comes from its Latin name "aurum." Human discovery and use of gold dates to pre...
Because gold is an element, a lump of pure gold contains nothing but gold atoms. Because pure gold is very soft and easily marred, it is often alloyed with other metals to make jewelry, coins and other precious objects.
Gold is a naturally occurring element on the periodic table and cannot be manufactured or made from other elements except through nuclear reactions. Gold is created when a star explodes to become a supernova or neutron s...
Gold normally has 79 electrons. Unless it has been ionized, the number of electrons in an atom is the same as its number of protons. This is expressed as the element's atomic number, which, for gold, is 79.
At normal room temperature, about 70 degrees Fahrenheit, gold exists in a solid phase. It is classified as a metal and must be heated to extreme temperatures to transform into a gas or liquid. It is a soft metal and is e...
