# ionization enthalphy

SAGAR SINGH - IIT DELHI

Dear gyanendra,

Amount of energy required to remove an electron from an isolated atom or molecule . There is an ionization potential for each successive electron removed, though that associated with removing the first (most loosely held) electron is most commonly used. The ionization potential of an element is a measure of its ability to enter into chemical reactions requiring ion formation or donation of electrons and is related to the nature of the chemical bonding in the compounds formed by elements.

All the best.

iam giving u the exact definition of ionization in simple words:::

enthalpy means exchange of heat,ionization enthalpy is defined as the heat evolved when any atom get ionized is called inonization enthalpy:

the ionization enthalpy of many elements has been given in the appendix of NCERT in back side

IEM is the ionization energy of the metal atom: $\text{M} + \text{IE}_\text{M} \to \text{M}^+ + \text{e}^-$

here electrons get ejected from the metal  atom
