Final answer:
A bond with an electronegativity difference of 0.2 is classified as a nonpolar covalent bond, where electrons are shared equally between the atoms.
Step-by-step explanation:
A bond between two atoms with an electronegativity difference of 0.2 is typically considered a nonpolar covalent bond. According to the rules for classifying chemical bonds, if the difference in electronegativity between two atoms is less than 0.5, the bond is generally nonpolar covalent.
This indicates that the electrons in the bond are shared fairly equally between the two atoms, and there is a balance in the distribution of electrical charge.
A bond is categorized as a nonpolar covalent, polar covalent, or an ionic bond based on the difference in electronegativity between the two bonded atoms.
In this case, if the electronegativity difference is equal to 0.2, it falls within the range of a nonpolar covalent bond, which is a type of covalent bond where the electrons are shared equally between the atoms.
