* Low melting and boiling point: Bromine is a liquid at room temperature, with a melting point of -7.2 °C and a boiling point of 58.8 °C. This makes it one of the few elements that exists as a liquid at room temperature.

* Diatomic molecule in the gas phase: Bromine exists as a diatomic molecule (Br₂) in the gas phase.

* Seven valence electrons: Bromine is in Group 17 of the periodic table, also known as the halogens. Halogens all have seven valence electrons.

* Readily reacts with metals to produce salt: Bromine is a highly reactive element and readily reacts with metals to form ionic compounds called salts. For example, it reacts with sodium to form sodium bromide (NaBr).
