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
what are the properites of gold
No. A "broken" atom of gold may be an ion, but it does not have the same chemical properties as an intact atom of gold.
Gold is very resistant to corrosion and is also very unreactive.
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.
Because gold melted or boiled remain gold, any chemical transformation occur.
When a gold bar is shaped into a wire, the gold's chemical properties do not change. Only the physical appearance changes when gold is changed in shape. Thus, this is an example of a physical change.
Gold is a specific chemical substance symbolized on the periodic table of chemical elements as Au with an atomic number of 79. Physical and chemical properties of gold can change depending on its present phase of matter (solid, liquid). Some of its properties include: * Metallic yellow (in its pure state); * Malleable; * Ductile; * Soft; * Shiny; * Oxidized states of -1, 1, 2, 3, 4, 5. Others can be found in more detail at the related links.
That's an atom of gold. An atom is the smallest representative particle of an element.

The chemical properties of calcium are most similar to (in between) the chemical properties of magnesium and strontium.
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.
it changes chemical properties
