the term 'isolated gaseous atom' is used in the definition of ionization enthalpy. Ground state of an atom refers to the most stable state of anatom. If an isolated gaseous atom is in its ground state, then less amount energy would be required to remove an electron from it., 
ground state means if the electron will be in n=1 state , in that state its more stable and having minimum energy
