iron and bromine
The two elements that are in KBr are Potassium and Bromine.
The name of the substance says it all. viz. Calcium and Bromine. There are NO other elements present.
NO!!! You have the question the wrong way around. The question should be ' Do elements make up minerals?'. The answer is YES!!!. e.g. The mineral iron ore is iron(III) oxide (Fe2O3) . It is made up of the elements iron (Fe) and oxygen(O).
There is NO such compound as 'Fe2O2'. The formula are 'Fe2O3' , and 'FeO'. In both cases the elements of combination are iron (Fe) and oxygen(O).
Iron is NOT made up of two elements. Iron is an element in its own right. It is found in the Periodic Table of Elements as 'Fe'. 'Fe' is the initials of the Latin name for iron, which is Ferrum. However, iron is mined as iron ore, which is an oxide of iron. It is a chemical combination of iron and oxygen. These are possibly the two elements you are thinking about. As oxides of iron can be found in different forms ( oxidation states). They Are. :- Fe3O4 ; Magnetite. (Lodestone of early navigation). Fe2O3 ; Iron (III) Oxide [ Ferric oxide) the common iron ore. FeO ; Iron (II) Oxide (Ferrous oxide) FeS ; Iron (II) Sulphide (Much less common. Iron metal is NOT found uncombined.
Potassium Bromide comprises of following elements: 1. Potassium 2. Bromine
iron and sulfur
There are two elements that make up the compound NaBr, or sodium bromide. These two elements are sodium and bromine.
The two elements that are in KBr are Potassium and Bromine.
Iron and oxygen
The elements present in silver bromide are silver and bromine.
Iron (Fe) and Sulfur (S) make up Iron Sulfide.
Iron and chlorine are the elements that make up ferrous chloride.
Iron and carbon.
Iron and oxygen
Ionic bond. The metal (iron) gives up electrons to the non-metal (bromine.)
Three chemical elements make up the Iron Triad, iron (Fe), cobalt (Co) and nickel (Ni).These three elements are sometimes given the name Iron Triad because they have some similarities in properties and are located together in the Periodic Table.
