Interpretation Introduction

(a)

Interpretation:

Lewis dot structure of the potassiumis to be drawn.

Concept introduction:

Lewis structure is a representation of a chemical formula of substance with valance electrons of atoms. The Lewis structures are also called electron dot structures. In the Lewis structure, electrons are denoted by dots. Only the valence electrons are presented as dots in the Lewis structure.

Answer to Problem 4.1E

The Lewis dot structure of potassium is shown below.

Chemistry for Today: General, Organic, and Biochemistry, Chapter 4, Problem 4.1E , additional homework tip  1

Explanation of Solution

The atomic number of potassium is 19.

Potassium belongs to the group I of the periodic table.

The electronic configuration of potassium is 1s22s22p63s23p64s1.

Hence, the number of electrons present in the valence shell of potassium is 1.

The Lewis dot structure of potassium is shown in Figure 1.
