Which of the following best describes a nonpolar covalent bond?
A
A bond where electrons are transferred from one atom to another.
B
A bond where electrons are shared unequally between two atoms.
C
A bond where atoms are held together by electrostatic forces.
D
A bond where electrons are shared equally between two atoms.
Verified step by step guidance1
Understand the concept of a covalent bond: A covalent bond is formed when two atoms share electrons to achieve a full outer electron shell.
Differentiate between polar and nonpolar covalent bonds: In a nonpolar covalent bond, the electrons are shared equally between the two atoms, whereas in a polar covalent bond, the electrons are shared unequally.
Recognize the characteristics of a nonpolar covalent bond: Nonpolar covalent bonds typically occur between atoms with similar electronegativities, meaning neither atom attracts the shared electrons more strongly than the other.
Identify examples of nonpolar covalent bonds: Common examples include the bonds between identical atoms, such as in diatomic molecules like O2 and N2, where the electronegativity difference is zero.
Review the options given in the problem: The correct description of a nonpolar covalent bond is 'A bond where electrons are shared equally between two atoms.' This matches the definition and characteristics discussed.
