Answer :
Ionization potential
The energy required to remove an electron from a neutral isolated gaseous atom and convert it into a positively charged gaseous ion is called ionisation potential. It is also called ionisation energy. The electron to be removed is valence electron. It is most loosely bound electron. The ionisation potential corresponds to the process X (g) → X + (g) + e −
Answer:Ionization Energy Trends in the Periodic Table. The ionization energy of an atom is the amount of energy required to remove an electron from the gaseous form of that atom or ion.
