Gold does not form compounds very readily.
Most known gold compounds are
Gold oxide, chloride, thiosulphate
double: Gold potassium cyanide, gold ammonium sulphite.

What are the chemical properties of gold?
Gold is called a noble metal because it resists reacting with stuff. But it can be "convinced" to react, and it forms numerous compounds. It's oxidation states range from -1 to +5, with +1 and +3, Au(I) and Au(III), far and away the most common. Gold will dissolve in Mercury, but creates an amalgam rather than react with it to create a compound. Aurum (gold) resists most acids, though aqua regia (a 3:1 mix of concentrated hydrochloric and nitric acids) will attack gold, as will cyanide. In the unusual -1 state, gold will form compounds like CsAu (cesium auride). It will hook up with the most reactive of the Group 1 and Group 2 elements, the Alkali and Alkaline Earth elements. Remember that the activity of these elements increases as you go down the column. That's just the opposite of the Group 17 elements, the halogens (fluorine, chlorine, etc.), whose reactivity increases as you go up the column. Speaking of the halogens, the Group 17 elements, will react with gold (Au), and auric fluoride (gold fluoride, AuFl) and auric chloride (gold chloride, AuCl) would be examples. Gold will form compounds in its +1 oxidation state with other ions, and it will also similarily form a number of compounds in the +3 oxidation state. There are also compounds (cluster compounds) where gold will form a compound that includes both the +1 and +3 oxidation states of the metal. It has "dual" (fractional) oxidation states in a single compound. Links are provided for more information.
What type of compounds has the lowest percent gold content by weight?
Those that do not contain gold at all -- a very long list!
How does mercury react with other elements?
Mercury forms amalgams with most metals. It can react with non-metals to form to types of compounds: mercurous and mercuric compounds.
Other name for phosphorus?
I don't believe there is another name for Phosphorus, but it can be spelled: PhosphorousActually, phosphorus and phosphorous are different things. Phosphorous is the adjectival form of P3+ valence, like how sulfur forms sulfurous and sulfuric compounds, its the same with phosphorus. It forms phosphorous compounds.
Osteoarthritis rheumatoid arthritis and gout are common forms of what?
Arthritis or rheumatism
What are facts and common compounds of gold?
The interesting fact is that gold is rather unreactive and forms very few compounds.
Does gold form compounds?
Although gold is unreactive, it forms many compounds with a range of oxidation states.
Does gold form ionic or covalent bonds when it forms a compound?
Ionic compounds
What common compounds oxygen forms?
Common compounds oxygen :- hypofluorous,ozonides,superoxides,oxygen difluoride,dioxygen difluoride,dioxygenyl
What common compounds contain gold?
There are no "common" compounds that contain significant quantities of gold. Gold is found in trace amounts in many things (seawater, for example). Gold is actually more commonly found uncombined, since it's fairly unreactive.
What are some common compounds made from silicon?
gold, boron, and magnesium :)
How many compounds are in gold?
gold is a pure substance = no compounds - Au
Which element forms max. no. of compounds?
Carbon is the element that forms maximum number of compounds
What compounds are gold in?
There is gold oxide, Au2O3 But gold usually does not form compounds
What is the most common compound that neon forms?
Neon is extremely inert and so far no compounds have been made from it.
What are common forms of treated or processed phosphate compounds?
phosphoric acid, triple superphosphate, ammonium phosphate, and superphosphate
What do sodium and nitrogen have in common?
Not a lot! Sodium is a reactive metal, nitrogen is an unreactive diatomic gas. Sodium forms compounds where it loses an electron, to form the Na+ ion. Nitrogen forms covalent compounds such as NH3 and ionic compounds where it gains three electrons to form the N3- ion.
