An element 'A' has two electrons in the outermost shell of its atom and combines with an element 'B' having seven electrons in the outermost shell, forming the compound `AB_(2)`. The compound when dissolved in water conducts electric current. Giving reasons, state the natrue of chemical bond in the compound.
