Question

classify each of the following particulate level illustrations as a representation of either an element or a compound. use the references to access important values if needed for this question.

Explanation:

Step1: Recall element - compound definitions

An element is a pure substance made of only one type of atom. A compound is a pure substance made of two or more different types of atoms chemically combined.

Step2: Analyze top - image

The top - image shows molecules with three atoms each, where there are two types of atoms (blue and white). So, it represents a compound.

Step3: Analyze middle - image

The middle - image shows molecules with two atoms each, and all atoms are of the same type (red). So, it represents an element.

Step4: Analyze bottom - image

The bottom - image shows molecules with two atoms each, and there are two types of atoms (red and blue). So, it represents a compound.

Answer:

Top image: Compound
Middle image: Element
Bottom image: Compound
