Final answer:
Chlorine gas (Cl₂) has a Lewis dot structure with a single covalent bond and six lone pairs on each atom, a linear shape, nonpolar bonds due to identical electronegativity, making it a nonpolar molecule.
Step-by-step explanation:
The molecule in question is chlorine gas, Cl₂. To determine its properties, such as Lewis dot structure, shape, and polarity, we consider its electron configuration and molecular geometry. For the Lewis dot structure, we have two chlorine atoms each sharing a pair of electrons to form a single covalent bond, with each chlorine atom completing its octet with three lone pairs of electrons. The shape of the Cl₂ molecule is linear because it consists of just two atoms. With regards to the bond polarity, as both chlorine atoms have the same electronegativity, the bond between them is nonpolar. And since the molecule is symmetrical, it is considered a nonpolar molecule. Therefore, the correct answer is B) Lewis dot structure, linear, nonpolar bonds, nonpolar molecule.
