What are compounds with 3 elements?
If the compound contains three elements one of which is oxygen then the compound name will end in –ate or –ite, eg Calcium carbonate contains calcium, carbon and oxygen.
Which is an example of a compound of an element?
Elements are represented by Symbols. b) Compound: A compound is a substance which contains two or more elements chemically combined together. Water is made up of hydrogen and oxygen atoms. Carbon dioxide is up of carbon and oxygen. Unlike elements , compounds can be decomposed, or broken down by simple chemical reactions.

How are the properties of a compound represented?
When the elements combine, some individual property of the elements is lost and the newly formed compound has new properties. Chemical Formula: Compounds are represented by their chemical formula. A chemical formula is a symbolic representation of the proportions of atoms that constitute a particular chemical compound.
