Properties and States of Bromine

The video tutorial explains the chemical formula for liquid bromine, highlighting its phases as both a liquid and a gas. Bromine is shown in a sealed container to prevent evaporation. The chemical formula for bromine, whether in liquid or gas form, is Br2, a diatomic molecule similar to oxygen (O2), nitrogen (N2), and chlorine (Cl2). The video concludes with a brief summary of bromine's properties.
