Chapter 8, Problem 8.43P

Interpretation Introduction

Interpretation:

The electronic configuration and the orbital diagram of the first excited state of sodium are to be determined.

Concept introduction:

The electronic configuration of an element tells about the distribution of electrons in the atomic orbitals. It is used to predict the physical, chemical, electrical and magnetic properties of the substance.

The spectral lines are the lines in the spectrum due to absorption and emission of light at a particular frequency. These are used to identify the elements and therefore called the fingerprints of the elements.
