Concept explainers
a.
Interpretation:
Lewis symbol for calcium should be written.
Concept Introduction: Lewis symbol is representation of an atom to show the number of valence electrons present in it. Some of the electrons involved in bonding and some remains as lone pair. The electrons are represented by dots surrounding the symbol of atom of the element.
b.
Interpretation:
Lewis symbol for sulfur should be written.
Concept Introduction: Lewis symbol is representation of an atom to show the number of valence electrons present in it. Some of the electrons involved in bonding and some remains as lone pair. The electrons are represented by dots surrounding the symbol of atom of the element.
c.
Interpretation:
Lewis symbol for silicon should be written.
Concept Introduction: Lewis symbol is representation of an atom to show the number of valence electrons present in it. Some of the electrons involved in bonding and some remains as lone pair. The electrons are represented by dots surrounding the symbol of atom of the element.
