Lewis Dot Structure Study Guide

True or False: The Lewis dot structure represents the valence electrons of an atom.

• True

• False

Answer explanation

True. The Lewis dot structure visually represents the valence electrons of an atom, showing how they are arranged around the atomic symbol.

True or False: Hydrogen always has two valence electrons in its Lewis dot structure.

• True

• False

Answer explanation

False. Hydrogen has only one valence electron in its Lewis dot structure, not two. It can form one bond by sharing this electron, which is why it is often represented with one dot.

True or False: Ionic compounds are represented in Lewis structures by sharing electrons.

• True

• False

Answer explanation

False. Ionic compounds are formed by the transfer of electrons, not by sharing them. Lewis structures typically represent covalent bonds, where electrons are shared between atoms.

True or False: Carbon typically forms four bonds in a Lewis structure.

• True

• False

True or False: Lone pairs of electrons are shown as pairs of dots in Lewis structures.

• True

• False

Answer explanation

True. In Lewis structures, lone pairs of electrons are indeed represented as pairs of dots, indicating that they are not involved in bonding.

True or False: Nitrogen typically forms three covalent bonds.

• True

• False

True or False: Double bonds involve four shared electrons.

• True

• False

True or False: Chlorine always forms one bond in a Lewis structure.

• True

• False

True or False: A triple bond is stronger than a single bond.

• True

• False

Answer explanation

True. A triple bond involves three pairs of shared electrons between atoms, making it significantly stronger than a single bond, which only involves one pair of shared electrons.
