Elements X and Y combine to make compound XY. Element Y has a greater number of electrons in its outer shell than element X. In the molten state, compound XY allows electricity to pass through it. Which row correctly gives the electron transfer that takes place during the reaction and the bonding type in compound XY?
- AX donates electrons to Y; ionic
- BX shares electrons with Y; covalent
- CY donates electrons to X; covalent
- DY shares electrons with X; ionic
