A bond in which electrons are pulled toward the more electronegative atom, creating partial charges, is described as which of the following?

• A. Covalent bond is polar
• B. Ionic bond is polar
• C. Metallic bond is polar
• D. Bond polarity

Answer: (D)

Bond polarity is the idea here. When two atoms with different electronegativities share electrons, the electrons are drawn more to the more electronegative atom, creating a partial negative charge on that atom and a partial positive charge on the other. This separation of charge characterizes the bond as polar. The description in the question matches bond polarity because it focuses on the unequal sharing of electrons and the resulting partial charges. The other options aren’t as accurate: a covalent bond can be nonpolar if the atoms have similar electronegativities; an ionic bond involves complete electron transfer with full charges rather than partial charges; metallic bonds feature delocalized electrons in a lattice and aren’t described by partial charges along a single bond.
