Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is insoluble in nitric acid alone, which dissolves silver and base metals, a property long used to refine gold and confirm ...
Measured strictly by monetary value, the two most expensive samples in the periodic table are this bar of gold, and the ten gram ampule of scandium. Both are worth well over a thousand dollars, and both were donated (the scandium outright, this bar on a semi-permanent loan basis). It's...
From its entry on the periodic table, it can be seen that the atomic number of Gold is 79, and its atomic mass is 196.967. The atomic number represents the number of protons in the nucleus of a gold atom — i.e., 79. The number of protons in an uncharged atom is equal to the ...

Gold is a chemical element with the symbol Au and atomic number 79 on the periodic table. Itis one of the few elements that occur naturally in a pure form, and it is known for its high resistance to corrosion and oxidation. The history of gold's use by humans dates back thousands of ...
The periodic table is a chart that shows how elements are related to one another. Gold is a heavy metal in a group known as the transition metals. Gold is also known as a precious metal (as are platinum and silver). Large amounts of gold are still used in the manufacture of coins,...
