The amount of energy needed to be supplied to an isolated atom in its gaseous and ground state to remove its most loosely bound electron to infinity is called ionization potential. Higher the value of Ionization Potential (IP), the more difficult it is to ionize the atom. Its SI unit is Joule (J). The commonly…
