Question

bohr model of cl₂ or lewis dot structures of cl₂ in a lewis dot structure, bonding electrons are represented by a pair of dots or a sing between the atoms. unshared electron pairs around the outside of the atoms are called nonbonding electrons or lone pairs. select the true statements. a chlorine molecule has one bonding electron. a single line between two atoms represents one shared electron. a chlorine molecule has 34 total electrons, 14 of which are valence electrons. there are six lone pairs in a chlorine molecule.

Explanation:

1. Analizar cada afirmación:

• "A chlorine molecule has one bonding electron": Incorrecto. En \( \text{Cl}_2 \), el enlace es un par de electrones compartidos (un enlace simple implica 2 electrones compartidos).
• "A single line between two atoms represents one shared electron": Incorrecto. Una línea simple representa un par de electrones compartidos (2 electrones).
• "A chlorine molecule has 34 total electrons, 14 of which are valence electrons": Un átomo de Cl tiene 17 electrones (7 de valencia). Dos átomos de Cl tienen \( 2 \times 17 = 34 \) electrones totales. La valencia: \( 2 \times 7 = 14 \). Esta es correcta.
• "There are six lone pairs in a chlorine molecule": Un átomo de Cl en \( \text{Cl}_2 \) tiene 3 pares no compartidos (lone pairs). Dos átomos: \( 2 \times 3 = 6 \) lone pairs. Esta es correcta.

Answer:

• A chlorine molecule has 34 total electrons, 14 of which are valence electrons.
• There are six lone pairs in a chlorine molecule.
