Solution

Enthalpy is defined as measurement of energy in thermodynamic system.the term enthalpy is usually aued as an alternative term for energy.
Ionisation energy is the energy needed to remove the outermost electron from the atom.
The metals are the ones in the left side of the periodic table.they loose electrons to obtain octat and to be stable.
so they dont want much energy to remove electrons from the outermost shell.so the have very low ionisation enthalpy.
