The image shows two and three overlapping balls, two balls touching externally, and two balls forming a figure shape.

A.
molecules of compounds
B.
molecules of elements
C.
molecules of mixtures
D.
molecules of water

Answer 1

B. molecules of elements

Reason: Each cluster is made of identical-looking balls, so each molecule contains only one kind of atom. That means they are molecules of elements (e.g., O2, O3), not compounds or water.
