# Nonmetals can be found in nature in the uncombined elemental form.
# Nonmetals can combine with other nonmetals to form compounds such as:
#* Carbon dioxide, CO<sub>2</sub>
#* Carbon monoxide, CO
#* Methane, CH<sub>4</sub>
#* Ammonia, NH<sub>3</sub>
# Fluorine is the most reactive of all the nonmetals.
# Nonmetals are poor conductors of heat and electricity.
# Nonmetals are not lustrous and are dull.
# Nonmetals are not ductile or malleable and brittle.
# Nonmetals have low densities.
# Seven of the nonmetallic elements exist as diatomic molecules. They are: 
#* the hydrogen molecule (H<sub>2</sub>)
#* the oxygen molecule (O<sub>2</sub>)
#* the nitrogen molecule (N<sub>2</sub>)
#* the fluorine molecule (F<sub>2</sub>)
#* the chlorine molecule (Cl<sub>2</sub>) 
#* the bromine molecule (Br<sub>2</sub>)
#* the iodine molecule (I<sub>2</sub>)
