Vedclass · Answer

(N/A) Ionization enthalpy is the energy required to remove an electron from an isolated gaseous atom in its ground state.
$1$. 'Isolated gaseous atom': In the gaseous state,atoms are far apart,which minimizes inter-atomic forces of attraction. By lowering the pressure,these forces are further reduced,allowing for a standardized measurement of energy changes without the influence of neighboring atoms.
$2$. 'Ground state': This refers to the lowest energy state of an atom. Since energy values depend on the electronic configuration,measurements must be taken from the most stable state to ensure consistency and comparability across different elements.

What is the significance of the terms 'isolated gaseous atom' and 'ground state' while defining the ionization enthalpy and electron gain enthalpy?
