Verified step by step guidance1
Understand the concept of chemical bonds: Chemical bonds are forces that hold atoms together in compounds. There are several types of bonds, including covalent, ionic, and metallic bonds.
Define a covalent bond: A covalent bond is formed when two atoms share electrons. This sharing can be equal or unequal, leading to different types of covalent bonds.
Differentiate between polar and nonpolar covalent bonds: In a nonpolar covalent bond, electrons are shared equally between the atoms. In a polar covalent bond, electrons are shared unequally, resulting in a partial charge on the atoms.
Identify the characteristics of a polar covalent bond: When electrons are shared unequally, one atom becomes partially negative (δ-) and the other becomes partially positive (δ+), creating a dipole moment.
Recognize the correct answer: Given the options, a polar covalent bond is the type of bond formed when electrons are shared unequally between two atoms.
