At the barest minimum, Iron and traces of Carbon.
The two elements that make up steel are mainly carbon and iron.
The two elements that make up steel are iron and carbon. Other elements can also appear in the steel, but these two are the ones that cause it to be called steel.
Steel contains Iron and Carbon. Various steels contain different compounds of the two plus other material to create different alloys.
Steel is Iron and Carbon. The two elements are present as elements not as a compound, just finely dispersed one in the other.
Iron is an element in its own right. So there are no two elements that make iron. However, Steel is an alloy of iron and carbon. Iron and Carbon are tweo different elements. So steel contains two different elements.
Iron and copper, steel and bronze are not elements.
It varies with the alloy. Bronze is an alloy of copper and tin; brass is an alloy of copper and zinc; steel is an alloy of iron and other elements, most commonly carbon.
When two or more elements bond together they form a compound.
When two or more elements bond together they form a compound.
It would form a compund. For example, the most famous coumpoud is H2O. This compound is made out of two Hydrogen molecules and one oxygen.
compound is when two or more elements combine chemically
After a chemical reaction two elements form a chemical compound.
