The longest wavelength of light that can be used for the ionisation of lithium atom (Li) in its ground state is x $\times$ 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 $\times$ 10$-$18 J ; h = 6.63 $\times$ 10$-$34 Js and c = 3 $\times$ 108 ms$-$1)
Answer (integer)
4
Solution
<p>Bohr model is not valid for lithium atom (Li) as Bohr model is valid for only single electronic species, so it would be valid for Li<sup>+2</sup> but not Li atom.
</p>
<p>So this question is <b>BONUS</b>.</p>
