Elements, Compounds, and Mixtures Quiz

What is a defining characteristic of an element?

• It is a pure substance with only one kind of atom.

• It can be broken down into simpler substances.

• It is always heterogeneous.

• It is made of multiple types of atoms.

What does the term 'homogeneous' mean in the context of elements?

• It means the element is a mixture.

• It means the element can be separated physically.

• It means the element is the same throughout.

• It means the element is made of different substances.

How are compounds different from elements?

• Compounds are always heterogeneous.

• Compounds are made of two or more different kinds of atoms.

• Compounds can be physically separated into their components.

• Compounds are made of only one type of atom.
