Sentences with phrase «hydrogen atoms»
Hydrogen atoms are the smallest units of hydrogen, which is a gas found in nature. They consist of a nucleus, which is a tiny particle, and an electron that orbits around it. Hydrogen atoms are the building blocks of hydrogen gas and are involved in chemical reactions to form compounds. Full definition
