Answer
A compound is a pure substance made up of two or more different elements [atoms] combined chemically in a fixed proportion.
In carbon dioxide, 1 atom of carbon combines with 2 atoms of oxygen to form one molecule of carbon dioxide [CO2], hence, we say that carbon and oxygen combine in a fixed ratio of 1:2 to form carbon dioxide.
