oxygen, nitrogen
A compound is composed of two or more elements. A compound of only two elements is a binary compound.
Two.(Two carbons, one oxygen so just two elements.)
If two elements are joined together it is a compound
A combination of two elements refers to a new substance created by combining two different elements. This combination may have different properties from the individual elements and can be achieved through various chemical reactions. These new substances can have unique characteristics and applications.
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.
Helium and Neon are considered the two most inert elements.
The set of elements that are elements of the two (or more) given sets is called the intersection of the sets.
No, elements are pure substances. However, if you mix two elements together, it depends on how well you mix them. Mixtures of two elements can be completely homogeneous, or extremely heterogeneous.
iron and gold
two numbers with a product of 1 are called elements
compound is when two or more elements combine chemically
After a chemical reaction two elements form a chemical compound.
