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.
The periodic table's name comes from the fact that it arranges the elements into repeating sets, otherwise known as "periods." These periods are defined by the covalence of an element, the number of electrons it has in i...
Gold is the 79th element on the periodic table and has a relative atomic mass of 196.967. Gold, which has a chemical symbol of Au, is a shiny, valuable metal that was first discovered more than 5,500 years ago.
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...
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...
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.
