which is a similarity between elements and compounds?\na. both contain atoms.\nb. both are mixtures.\nc. both are chemically combined.\nd. both contain two or more substances.

Answer

Brief Explanations:

Elements are made of one - type of atom, and compounds are made of two or more types of atoms chemically combined. So, both contain atoms. Elements are not mixtures, not all are chemically combined in the sense of compounds (elements are pure substances with one - type of atom), and elements do not contain two or more substances (compounds do).

Answer:

A. Both contain atoms.
