Expert Answer
The amount of energy required for converting one mole of gaseous sodium atom into sodium ions in the gaseous state is called ionization enthalpy (I.E.). Ionization energy, Ionization potential, and Ionization enthalphy are the same thing.
The electron affinity of an element is the energy given off when a neutral atom in the gas phase gains an extra electron to form a negatively charged ion. A fluorine atom in the gas phase, for example, gives off energy when it gains an electron to form a fluoride ion.
