Gold, like other precious metals, is measured in troy weight; when alloyed with other metals, the term carat is used to express the amount of gold present, 24 carats being pure gold. For many years the value of gold was set by the U.S. at $20.67/troy ounce; in 1934 this value was fixed by law at $35.00/troy ounce, 9/10th fine.
Gold atoms have 79 electrons and the shell structure is 2.8.18.32.18.1. The ground state electronic configuration of neutral gold is [ Xe ]. 4f14. 5d10. 6s1 and the term symbol of gold is 2S1/2.

Gold is an excellent conductor of heat and electricity. It is a soft, yellow, metal with a beautiful lustrous sheen. It is the most malleable and ductile of all the elements and a single gram can be beaten into a sheet one square meter sheet of gold leaf. Gold, the 79th element on the Periodic Table of the Elements, is one of the more recognizable of the bunch.
Gold atoms have 79 electrons and 79 protons with 118 neutrons in the most abundant isotope.

Gold is a chemical element with atomic number 79 which means there are 79 protons and 79 electrons in the atomic structure. The chemical symbol for Gold is Au. Gold is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. Gold is a transition metal and a group 11 element.
You can tell the characteristics of an element by looking at its location on the table.

Like other transition metals, gold is in the middle of the periodic table. It is the only metal that has a distinctive yellow metallic appearance in pure form, although there are other elements that oxidize to develop a golden tint. While most metals are hard, pure gold is actually quite soft. The metal is easily drawn into a wire (ductile), hammered (malleable), and is one of the best conductors of heat and electricity.
