            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°.

If it releases 5 tons a day and there are 7 days a take that answer and multiply by 5 percent (0.05) to find the amount released in one week. leave a comment if you need more .
