What I Have Learned
Elements and compounds are all substances. They can be classified based on
their number of atoms. Since element is the simplest form of matter it has one atom
only and cannot be broken down anymore. Compounds are combinations of two or
more elements; thus, it composes of two or more atoms then it can be broken into
its components, the elements.
