Evaluate the statement. bromine (br) is a halogen. given the information in the statement, what can be inferred as true about bromine? hint: look at your periodic table. a) bromine has seven electrons and seven protons b) bromine tends to form covalent bonds when in chemical reactions with metals c) bromine tends to form anions when in chemical reactions with metals d) bromine does not react easily with other atoms.

            Option-C (Bromine tends to form anions when in chemical reactions with metals) is the correct answer.

Explanation:
                   Bromine belongs to Group VII called as Halogens in the periodic table. It has seven valence electrons in its valence shell. In order to obtain noble gas configuration, Bromine tends to gain one electron from metals.
                   Therefore, Bromine forms ionic bond when treated with metals as the electronegativity difference is greater than 1.7. When Bromine gains electron from any metal it converts into Bromide (Br⁻) as follow,

                                     M +  Br₂      →     MBr₂

Reduction of Bromine,

                                     Br₂  +  2 e⁻     →     2 Br⁻     ∴ Br⁻  =  Anion

Oxidation of Metal:
                                     M     →     M²⁺  +  2 e⁻

Noble gases is far right
