What property is described as an atom's ability to attract shared electrons?

The term that describes an atom’s ability to attract shared electrons is electronegativity. It is a measure of the tendency of an atom to attract a bonding pair of electrons. When two atoms come together to form a bond, the atom with higher electronegativity will attract the shared electrons closer to itself, resulting in a polar covalent bond if the atoms involved are different.

For example, in a molecule of hydrogen chloride (HCl), chlorine is more electronegative than hydrogen, causing the shared electron pair to be drawn closer to the chlorine atom. This unequal sharing of electrons leads to a dipole moment in the molecule, highlighting how electronegativity plays a crucial role in determining the nature of bonds and the overall behavior of molecules.

In contrast, bond length refers to the distance between the nuclei of two bonded atoms and does not relate to the attraction of electrons. Bond energy refers to the energy required to break a bond, which also does not concern the attraction of shared electrons. Bond polarity, while related to differences in electronegativity, specifically describes the separation of charge in a bond resulting from this attraction but is not the fundamental property that defines it. Thus, the correct choice emphasizes the inherent property of electronegat
