Seventeen elements are generally classified as nonmetals; most are gases (hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon and radon); one is a liquid (bromine), and a few are solids (carbon, phosphorus, sulphur, selenium, and iodine).
Homonuclear Diatomic Molecules. There are seven elements that occur naturally as homonuclear diatomic molecules. All of these molecules are in the gaseous state. Five of these elements-hydrogen, nitrogen, oxygen, fluorine, and chlorine-occur as diatomic elements at room temperature, which is 25 degrees Celsius.he subscript 2 of oxygen and nitrogen indicates the number of oxygen atoms and nitrogen atoms. So the oxygen molecules present in the atmosphere have two oxygen atoms and the nitrogen molecules have two nitrogen atoms. There are also other diatomic molecules that we encounter every day.
