Answer:

Potassium bromide is a strong electrolyte as it can be entirely disassociated in aqueous solution. The problem with this question is that you can't really have an aqueous solution of calcium oxide, CaO, because this compound will react with water to form calcium hydroxide, Ca(OH)2. Keep in mind that this reaction is highly exothermic!

Explanation:

Elements are held together (joined) by a chemical bond. These bonds differ with the property of the element. Metals usually bond by transfer of electrons whereas metalloids usually share electrons to make a bond.
