Question

What is the relationship between elements ,atoms ,and compounds

Answer 1

Elements are pure substances made up of only one kind of atom, they are pure substances. Compounds are made up of two or more elements chemically combined, and all of those have atoms. 

Answer 2

Elements are separate particles that contain the properties of only one type of element (pure substance) and an atom represents that element as the smallest non divisible particle that retains the properties of that element. Compounds can be formed by conjoining different atoms together in different ratios and shapes, so a combination of elements.
