Can someone me with this? 20 pts. calcium and bromine would join with a(n) bond and sulfur and oxygen would join with a(n) bond. a. ionic, ionic b. ionic, covalent c. covalent, ionic d. covalent, covalent

Calcium and Bromine, (Calcium Bromide/ CaBr2) has an Ionic Bond, whereas Sulfur and Oxygen (Sulfur Oxide/SO2) has a covalent bond.

Covalent bonds are formed via two nonmetals, and are bonded via electrons. Meanwhile, ionic bonds are formed via ions.

Your answer would be B.) Ionic, Covalent.

Hope this helped! :)

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
