Question

Define ionization energy of 1 and ionization energy of 2 why is ionization energy of 2 greater than ionization energy of 1 for a given atom discuss the factors that affect the ionization energy of an element

Answer 1

The 2 ionization energy is greater than 1 because if we remove one electron from an atom effective neuclear charge increases than it is very difficult to remove 2nd electron.
