The energy required to remove an electron from the gaseous atom is known as Ionization enthalpy . The energy required to remove the 1st electron from an isolated atom is called first ionization enthalpy . Thus, it is a quantitative measure of how much a gaseous atom is capable of losing its electrons. In chemistry, ionization enthalpy is mainly influenced by two factors: (i) Repulsive forces between electrons and (ii) Attractive forces between electrons and the nucleus. Moreover, in this ... Second ionization enthalpy of 3d elements Second ionization enthalpy is the energy required to remove second outermost electron from a cation (with +1 charge) in gaseous state. The second ionization enthalpy also shows very irregular trend in 3d metals. Anand Classes explains Ionization Enthalpy , its definition, units, successive ionization , factors, and FAQs for JEE & NEET preparation.
