Question

label elements, compounds, and mixtures - k
each circle represents an atom and each different color represents a different kind of atom. if two atoms are touching, then they are bonded together.
choose the best classification.
element
compound
mixture of elements
mixture of compounds
mixture of elements and compounds

Explanation:

An element is a pure substance made up of only one type of atom. In the given diagram, all the atoms (represented by circles) are of the same kind (same color, no indication of different atoms). A compound consists of two or more different types of atoms chemically bonded. A mixture (of elements, compounds, or both) would have different distinct substances. Since there's only one - type of atom (no different atoms or combination of different substances), it fits the definition of an element.

Element
