Chapter 13, Problem 110A

Interpretation Introduction

(a)

Interpretation:

The electrons in energy level are to be written and electron dot structure is to be drawn.

Concept introduction:

Electrons in energy level are calculated by writing electronic configuration.

Electron dot structure is drawn by writing the symbol of the structure and putting the dots on the symbol as there are valence electrons in that element.
