Glucose is made of carbon, oxygen, and hydrogen atoms.

#### Explanation:

Glucose is an organic compound composed of only three elements: carbon, hydrogen, and oxygen.

You can determine how many atoms of each type form a glucose molecule by looking at glucose's molecular formula, ${C}_{6} {H}_{12} {O}_{6}$.

Ths ubscripts each type of element has in the molecular formula will tell you how many atoms each contributes to the molecule. In your case, every molecule of glucose contains 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. Here's how a glucose molecule looks like

Five of the six carbon atoms and one of the six oxygen atoms form a ring structure. The remaining carbon is attached to one of the carbons that are next to the ring oxygen.

The remaining five oxygen atoms form hydroxide groups attached to the rest of ring carbons.
