Explanation:

Step1: Recall definitions

• Element: Consists of only one type of atom.
• Compound: Consists of two or more different atoms chemically bonded.
• Mixture: Consists of two or more substances (elements or compounds) physically combined. A homogeneous mixture has a uniform composition, while a heterogeneous mixture has a non - uniform composition.

Step2: Analyze the third picture

Assuming the third picture has only one type of atom (since no other information about the picture is given except the options). If there is only one type of atom, it fits the definition of an element.

Answer:

Element
