Define ionization enthalpy with an example.

Text Solution

Verified by Experts

lonization enthalpy may be defined as the amount of energy required to remove an electron from an . isolated gaseous atoin in its ground state. For example,
`Ng(g)+"Energy"toNa^(+)+e^(-)`
The energy which is required to remove an electron from sodium atom is called ionization enthalpy. It is represented by 1.E.,
