it is the energy required for a mole of atom to loose a mole of electron.
Ionisation Enthalapy is the amount of energy required to remove the outer most electron from a gaseous atom in its ground state.
The ionisation enthalpy of potassium is lower than that of sodium.
yes, it is correct.
Helium
This value is identical for isotopes.
Oxygen has a lower electronegativity than fluorine (3.5 as compared to 4).

atoms having low Ionisation enthalpy and ones having high electronegativity form ionic bond
Due to low ionisation enthalpy, metals easily lose an electron and attain positive charge. eg. Na+, K+
The properties like electronegativity , ionisation energy , enthalpy changes vary periodically with atomic number.
noble gases have the maximum ionisation energy. helium has the highest ionisation energy
in a period size decreases from left to right and hence electrons are more tightly held to the nucleus. so electron gain enthalpy increases across a period . down the period size increases and thus in general electron gain enthalpy decreses .
