Look at the location of elements A,B,C,and D in the following periodic table.Consider the oxides that form when the elements A-D are in their highest oxidation states. 
-Which oxide is the most covalent?
A)A 
B)B 
C)C

Quizplus · Accepted Answer

Covalent character in oxides increases with electronegativity difference between the two atoms. Since C is located in the upper right corner of the periodic table and has the highest electronegativity among the given elements, its oxide is expected to be the most covalent. Therefore, Choice C is the best answer.
