Ionisation energy is the amount of energy required to remove the outermost e^(-) from a gaseous atom. It's unit is kJ/mole or kcal/mole. Successive ionisation energy - It is the amount of energy required to remove electron successively from a gaseous ion. These are termed as IE_(2), IE_(3), IE_(4) etc. the difference in the values of IE_(1), IE_(2) " and " IE_(3) helps to determine electronic configuration of the element.
