Question

difference between ionization enthalpy and enthalpy of atomization

Answer 1

Ionization enthalp is the energy required to remove an electronic whereas enthalpy of atomization is the energy required to separate atoms

Answer 2

Answer:

Ionization enthalpy is about removing an electron from an atom.

Enthalpy of atomization is about separating all the atoms from a molecule.

Explanation:

Enthalpy of atomization is defined as the energy required to separate all the atoms from molecules in the gaseous phase. It is represented as $\[{\Delta _a}{H^o}\]$.

For example enthalpy of atomization of methane is 1665KJ/mol

$\[C{H_4}\left( g \right) \to C\left( g \right) + 4H\left( g \right){\text{ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ }}{\Delta _{\text{a}}}{{\text{H}}^{\text{o}}} = 1665KJ/mol\]$

Enthalpy of ionization is defined as the energy required to take out an electron from an isolated atom in the gaseous phase. For example, the first ionization enthalpy of sodium is 5.14eV.
