Explanation:
The given data is as follows.
Energy needed for 1 mole = 279.7 kJ =
= 279700 J
Therefore, energy required for 1 atom will be calculated as follows.
=
As relation between energy and wavelength is as follows.
E =
where, h = planck constant =
c = speed of light =
= wavelength
Therefore, putting given values into the above formula as follows.
E =
=
=
or, = m
= 428 nm
Thus, we can conclude that the maximum wavelength of light that can remove an electron from an atom on the surface of lithium metal is 428 nm.
