nothing, its nothing at all
The answer is acids.... "acids are most broadly defined as compounds that are electron pair acceptors."
Both. Bromine gains one electron in ionic compounds. Bromine will share electron in covalent compounds.
These are the covalent compounds.

gold is a pure substance = no compounds - Au
It has metallic compounds (metal-metal), and it will also combine with nearly anything that can gain an electron (polyatomic ions, non-metals). It doesn't react very well or often due to its electronegativity.
gold (Ag) is a pure element, so the electrons just orbit the nucleus in the electron cloud. But salt is a compound of sodium plus chloride (NaCl). these elements are bonded together in an Ionic bond, so Sodium (Na) loses an electron, and that electron is transferred to chloride (Cl), this way both elements have 8 valence electrons. In short, gold's electrons orbit the nucleus, and in salt, sodium gives an electron to chloride so they can both have 8 valence electrons.
Gold does not form compounds very readily. Most known gold compounds are Gold oxide, chloride, thiosulphate double: Gold potassium cyanide, gold ammonium sulphite. The compounds decompose very readily at low temperatures.
There is gold oxide, Au2O3 But gold usually does not form compounds
Gold is an element, not a compond. It is not made of anything, although many compounds are made from gold.
Compounds of Gold are often called Auric compounds and for a list see the related link.
Lithotrophs are organisms that use inorganic compounds as electron donors in cellular respiration.
