Answer:
The shape and bonding in a diatomic bromine molecule is best described as Symmetrical and Non-Polar.
Explanation:
Remember polarity is induced due to Electronegativity Difference between two bonded elements. Br₂ is non polar because the electronegativity difference between two Bromine atoms is zero, i.e.
E.N of Bromine 1 = 2.96
E.N of Bromine 2 = 2.96
-------------
Difference = 0.00
Secondly, bromine molecule is symmetrical in shape. Any object which repeats its structure when rotated at 360° is said to be symmetrical in nature. So, Br₂ when rotated repeats its face at 180°.
