Ionization Energy | Periodic Trends

This lecture is about ionization energy and periodic trends of ionization energy on periodic table. Q: What is ionization energy? Ans: The minimum amount of energy required to remove the outermost electron of an isolated neutral gaseous atom to form a cation is called ionization energy. For example, when you provide 738KJ/mol energy to the Magnesium atom, it will lose its outermost electron and become cation. This 738KJ/mol energy is called ionization energy. #ionizationenergyy #firstionizationenergy #secondionizationenergy Subscribe my channel at:   / @najamacademy   Youtube link:    / @najamacademy   Facebook link:   / najamacademy
