If one electron has been removed from an atom, it becomes increasingly difficult to remove the second and subsequent electrons from the resulting positively charged ions on account of electrostatic attraction. The numerical value of energy involved in the given process K→K− is less than that of which of the following processes?

Answer» If one electron has been removed from an atom, it becomes increasingly difficult to remove the second and subsequent electrons from the resulting positively charged ions on account of electrostatic attraction. The numerical value of energy involved in the given process $K \to K^{-}$ is less than that of which of the following processes?
