Bromine is a nonmetal. It belongs to the halogen group in the periodic table, which consists of elements that are typically nonmetals. Bromine is a liquid at room temperature and is known for its reddish-brown color and strong, unpleasant odor.
Nonmetals are elements that lack the characteristics of metals. They are generally poor conductors of heat and electricity, and they tend to be brittle in solid form. Bromine fits these characteristics, as it is not a good conductor and is not malleable or ductile like metals.
In summary, bromine is classified as a nonmetal due to its physical and chemical properties, which align with those of other nonmetals in the periodic table.
