The longest wavelength of light that can be used for the ionisation of

1.	The longest wavelength of light that can be used for the ionisation of lithium atom (Li) in its ground state is x × 10-8 m. The value of x is (Nearest Integer)(Given: Energy of the electron in the first shell of the hydrogen atom is -2.2 × 10-18 J; h=6.63 × 10-34 Js and c = 3 x 108 ms-1)
Answer» Correct answer is 4 We can not calculate I.E. of lithium atom.
