Verified step by step guidance1
Identify the molecule in question: Br2 is a diatomic molecule consisting of two bromine atoms bonded together.
Determine the number of atoms and electron pairs around the central atom: In Br2, there are only two atoms and no central atom with additional bonded atoms or lone pairs to consider.
Recall the VSEPR theory principle: The shape of a molecule is determined by the repulsion between electron pairs around the central atom, but in diatomic molecules, there is only a single bond and no lone pairs affecting geometry.
Conclude the molecular geometry: Since Br2 consists of only two atoms connected by a single bond, the molecule is linear by default, with a bond angle of 180°.
Therefore, according to VSEPR theory, the molecular geometry of Br2 is linear.
