Choose the covalent compounds from the following choices br2 mgs so2 kf

Types of Bonds can be predicted by calculating the difference in electronegativity.

If, Electronegativity difference is,

                Less than 0.4 then it is Non Polar Covalent Bond

                Between 0.4 and 1.7 then it is Polar Covalent Bond

                Greater than 1.7 then it is Ionic

For Br₂;

                    E.N of Bromine      =   2.96

                    E.N of Bromine      =   2.96

                    E.N Difference             0.00          (Non Polar Covalent Bond)

For MgS;

                    E.N of Sulfur               =   2.58

                    E.N of Magnesium      =   1.31

                    E.N Difference                  1.27          (Ionic Bond)

For SO₂;

                    E.N of Oxygen      =   3.44

                    E.N of Sulfur          =   2.58

                    E.N Difference             0.86          (Polar Covalent Bond)

For KF;

                    E.N of Fluorine          =   3.98

                    E.N of Potassium      =   0.82

                    E.N Difference                3.16          (Ionic Bond)

Result: The Bonds in Br₂ and SO₂ are Covalent in Nature.

it is the most commonly accepted one

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.
