Is bromine a solid?

Bromine is a deep-red liquid at room temperature. Below 19 degrees Fahrenheit, bromine is a solid.


The fact that bromine is a halogen and located in group 17 of the periodic table is evidence that the element is a nonmetal. However, bromine’s position on the periodic table is not indicative as to whether or not the element is a liquid or a gas at room temperature. This can be determined by the element’s melting and boiling points. Room temperature is about 70 degrees Fahrenheit. Bromine has a melting/ freezing point of 19 degrees Fahrenheit (-7.2 degrees Celsius). This means that when bromine is below 19 degrees Fahrenheit, it is a solid. However, when bromine is above 19 degrees Fahrenheit, bromine changes from a solid to a liquid. The boiling point of bromine is 137.8 degrees Fahrenheit (58.8 degrees Celsius). At its boiling point, bromine changes from a liquid to a gas. Thus, between 19 degrees Fahrenheit and 137.8 degrees Fahrenheit, bromine is a liquid.
