Chapter 8, Problem 8C.4P

Interpretation Introduction

Interpretation:

The energy levels of lithium ion are of the form $-hc{\tilde{R}}_{\text{Li}}/n^2$ has to be shown. The value of ${\tilde{R}}_{\text{Li}}$ for ${\text{Li}}^{2+}$ ion has to be calculated. The wavenumber of the two longest-wavelength transitions of Balmer series of the ion have to be predicted. The ionization energy of ${\text{Li}}^{2+}$ has to be calculated.

Concept introduction:

An atom is made up of three subatomic particles-neutrons, protons, and electrons. Neutron and protons are present in the nucleus of the atom, whereas electrons are revolving outside the nucleus in an atom. An electron can excite or relax from one energy level to another energy level.
