Question

A(n)_________contains only one type of atom, whereas a(n)_________ is composed of two or more different elements bonded together. A(n)___________ also contains more than one substance, but these can be separated by physical means, whereas the components of a compound cannot.

Answer 1

Answer:

1. Element

2. Compound

3. Mixture

Explanation:

Elements and compounds are both pure substances. ELEMENTS are substances that contain only one type of atom. For example, Cl2 contains only chlorine atoms. COMPOUNDS, on the other hand, contain atoms of two or more elements that are chemically joined together. For example, CaCl2 contains atoms of calcium and chlorine.

MIXTURES are another kind of substances that contains more than one substances, however, unlike compounds, they are not chemically joined. Mixtures can easily be separated by physical means.
