Which of the following would most likely form an ionic bond with an ion of calcium? select one: a. potassium b. magnesium c. bromine d. sulfur

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

                Between 0.4 and 1.7 then it is Polar Covalent 

                Greater than 1.7 then it is Ionic

For Ca and K,

                    E.N of Calcium           =   1.00

                    E.N of Potassium        =   0.82

                    E.N Difference                  0.18          (Non Polar Covalent)

For Ca and Mg,

                    E.N of Magnesium       =   1.31

                    E.N of Calcium            =   1.00

                    E.N Difference                   0.31          (Non Polar Covalent)

For Ca and Br,

                    E.N of Bromine            =   2.96

                    E.N of Calcium            =   1.00

                    E.N Difference                   1.96                 (Ionic)

For Ca and S,

                    E.N of Sulfur                =   2.58

                    E.N of Calcium            =   1.00

                    E.N Difference                   1.58          (Polar Covalent)

Result:

          The bond between Calcium and Bromine is Ionic in Nature.

the answer is: they rebelled against saddam hussein’s rule.

kurds opposed saddam rule and wanted independence. kurds in the north and shiites in the south revolt against hussein.

for example, the halabja attack in 1988 conducted against the kurdish people by the iraqi regime under saddam hussein, where between 4000 people are killed and around 9000 are injured.
