What are Lewis symbols?

What are Lewis symbols?

• A. Diagrams that show the total number of protons in the nucleus.
• B. Diagrams that illustrate electron orbitals energy levels.
• C. Diagrams that represent the valence electrons as dots around the element symbol.
• D. Diagrams that indicate bond angles in molecules.

Answer: (C)

Lewis symbols are diagrams that represent the valence electrons as dots around the element symbol. The number of dots shows how many valence electrons the atom has, and unpaired dots indicate available electrons for bonding while paired dots show electrons already paired in the outer shell. This simple visualization helps explain how atoms bond to form molecules and why elements tend to form certain numbers of bonds or follow the octet rule (with some elements showing expanded octets). Bonds are often depicted as lines connecting pairs of dots to show shared electrons. They don’t show inner-shell electrons, the nucleus, energy levels, or bond angles—those are not the focus of Lewis symbols.
