Chapter 12, Problem 24CR

Interpretation Introduction

Interpretation:

Valance electrons in an atom should be defined and discussed. Importance of valance electrons to an atom’s chemical properties than the core electrons or nucleus should be discussed.

Concept Introduction:

There are two types of electrons in an atom: valence and core electrons. Valence electrons are electrons that occupy the outermost principal energy level of an atom while core electrons are electrons that occupy the innermost principal energy levels.
