Molecular Geometry of Br2

The video tutorial explains the molecular geometry of bromine gas (Br2). It begins with the Lewis structure, showing shared and lone pair electrons. The molecular geometry of Br2 is linear with a bond angle of 180 degrees. The video further explains that with more than two atoms, molecular geometry becomes complex, often requiring a chart to determine the steric number and lone pairs. The tutorial concludes with a reference to additional resources for understanding molecular geometry.
