उत्तर
Ionisation Enthalpy or potential is highest on the right side of the periodic table and lowest on the left side. Elements X and Y seem to be metals, which are on the left side of the table. Group I metals lose one electron each. Ionisation Enthalpy decreases in groups from top to bottom. In the IA group, X represents Sodium (Na) and Y represents Caesium (Cs). Also, X is in the third period and Y is in the sixth.
