Which statement is true about nitrogen and oxygen?

Hello. This question is incomplete. The full question is:

"Which statement is true about nitrogen and oxygen? A. They make up about 99.9% of the human body. B. They are both made of protons, neutrons, and electrons. C. They are both used to make water molecules. D. Neither contains subatomic particles."

Answer:

B. They are both made of protons, neutrons, and electrons.

Explanation:

Nitrogen and oxygen are elements known to all of us. An oxygen molecule is an oxygen atom and a nitrogen molecule is a nitrogen atom.

As we know, all atoms are formed by three particles: protons, neutrons and electrons. For this reason, we can say that both oxygen and nitrogen are composed of protons, neutrons and electrons. For this reason, the letter B is the correct alternative.

Nitrogen and Oxygen are both gases in the atmosphere.
