A compound is a substance made from the combination of two or more elements and held together by chemical bonds that are difficult to break. The bonds form as a result of sharing or exchanging electrons between atoms.
A compound (chemical compound) is formed when different elements react, forming bonds between their atoms.
A molecule is the smallest indivisible unit of a compound that retains its chemical properties.
Different elements react and form bonds between their atoms to create a compound.
Compounds have unique properties that are different from the properties of their constituent elements.
Introducing a new element to a compound can lead to additional reactions and the formation of new compounds.
