Which would most likely be joined by an ionic bond?

Aa positive metal ion and a positive nonmetal ion
Ba positive metal ion and a negative nonmetal ion
Ca negative metal ion and a positive nonmetal ion
Da negative metal ion and a negative nonmetal ion

Verified Answer :

b) a positive metal ion and a negative nonmetal ion. 


Because generally ions of non-metal elements (such as the halogens) are negatively charged while ions of metal elements (such as the alkali earth metals) are positively charged. The differences in their changes causes strong electrostatic attraction (an ionic bond).
