Which of the following best describes the polarity of a nitrogen molecule (N_2)?
A
N_2 is a nonpolar molecule because it contains a lone pair of electrons.
B
N_2 is a polar molecule due to its linear shape.
C
N_2 is a nonpolar molecule because it consists of two identical atoms sharing electrons equally.
D
N_2 is a polar molecule because the nitrogen atoms have different electronegativities.
검증된 단계별 안내1
Step 1: Understand the concept of molecular polarity, which depends on the difference in electronegativity between atoms and the molecular geometry.
Step 2: Recognize that nitrogen molecule (N\_2) consists of two identical nitrogen atoms bonded together.
Step 3: Since both atoms are identical, they have the same electronegativity, meaning the electrons are shared equally in the bond.
Step 4: Because the electron distribution is equal and the molecule is linear and symmetrical, there is no net dipole moment.
Step 5: Conclude that N\_2 is a nonpolar molecule due to equal sharing of electrons between two identical atoms.
