Describe the relationships between molecules, atoms, and a grain of sugar.

Atoms make up molecules, which make up grains of sugar.

Answer:All matter in is a massive collection of molecules. Molecules are a joining of two of more atoms, which are the most basic unit of physical matter. Atoms are given a different weight based on the number of protons and neutrons in the nucleus and electrons in the surrounding cloud. The same electromagnetic force that keeps a single atom together can also hold two or more atoms together to form a molecule, while numerous molecules join together to form matter.
