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.
go to the link below and it will tell you all the chemical properties of tungsten:
Salt is a chemical compound. It has chemical and physical properties.
as the elements in a group have the same number of valence electrons, their chemical properties will be similar (with few exceptions of course)
chemical property is any of a material's properties that becomes evident during a chemical reaction
no
Gold is more stable. It isn't very reactive and doesn't form many bonds. It has 79 protons and 118 neutrons. The sixth energy level has one valence electron. It can be found in a natural bond known as gold ore. Gold's symbol is Au.
Gold is very resistant to corrosion and is also very unreactive.
Au3P is the chemical formula for gold(I) phosphaethyne, a compound containing gold and phosphorus. It is a rare and unstable compound that has been studied for its unique chemical properties.
Yes, a broken atom of gold still retains the properties of gold. The properties of an element are determined by its atomic structure, so even if an atom is broken apart, it still contains the same number of protons, defining it as gold.
Because gold melted or boiled remain gold, any chemical transformation occur.
The chemical symbol of gold is Au, which comes from the Latin word "aurum." It is a precious metal known for its valuable properties such as resistance to corrosion and conductivity.
That's an atom of gold. An atom is the smallest representative particle of an element.
Gold iodide is a chemical compound formed by the combination of gold and iodine. It is typically a yellow to orange solid that can be used in some chemical reactions or as a theoretical model for studying the properties of certain materials.
Liz is the coolest person :) <3
Forming a bar of gold into wire is a physical change. This is because the gold is being physically reshaped without undergoing a chemical reaction. The properties and composition of the gold remain the same throughout the process.

Yes, chemical properties can be determined only experimentally, as a consequence of chemical reactions. But, today chemists can made some predictions about chemical properties of a substance on the basis of existing data about chemical and physical properties.
