Solution
The correct option is C
Remove one mole of electrons from one mole of monovalent gaseous cations of the element
The first ionization energy is the energy required to remove one mole of the most loosely held electrons from one mole of gaseous atoms to produce 1 mole of gaseous ions each with a charge of 1+
Second ionization energy is defined by the equation: It is the energy needed to remove a secondelectron from each ion in 1 mole of gaseous 1+ ions to give gaseous 2+ ions.
