The correct response is **an alkali metal and a halogen**.
In this type of reaction, the alkali metal (which has one electron in its outer shell) loses that electron and becomes a cation, while the halogen (which needs one electron to complete its outer shell) gains that electron and becomes an anion. This is a common type of ionic bonding.
