Concept explainers
Interpretation:
The importance of valence electrons needs to be explained.
Concept introduction:
Valence electrons are those which are present in the outermost shell of an atom.

Answer to Problem C4.1RE
Valence electrons contribute to the chemical reactivity. The chemical nature of an element can be explained on the basis of valence electrons present in the valence shell of its atom.
Explanation of Solution
Valence electrons participates in
Valence electrons are important as these control the chemical reactivity of an atom.
