Chapter 5.3, Problem 26PP

a.

Interpretation Introduction

Interpretation: Electron dot structure for an atom of Magnesium needs to be drawn.

Concept introduction: Electron dot structure represents the valence electrons around the elements. The electrons are denoted as dots around the symbol of the element.

Answer to Problem 26PP

Magnesium $\left[Ne\right]3s^2$ ( $2$ valence electron)

  

Explanation of Solution

The electron dot structure for an atom is a representation of the valence shell electrons in an atom. It shows how the electrons are arranged around the atom. Electrons are presented as dots around the symbol of the element.

Magnesium $\left[Ne\right]3s^2$ ( $2$ valence electron)

b.

Interpretation Introduction

Interpretation: Electron dot structure for an atom of Thallium needs to be drawn.

Concept introduction: Electron dot structure represents the valence electrons around the elements. The electrons are denoted as dots around the symbol of the element.

Answer to Problem 26PP

Thallium $[Xe]4f^{14}5d^{10}6s^{2}6p^1$ ( $3$ valence electron)

  

Explanation of Solution
