Verified step by step guidance1
Identify the types of chemical bonds: covalent, ionic, and metallic. Covalent bonds involve the sharing of electrons, ionic bonds involve the transfer of electrons, and metallic bonds involve a 'sea' of electrons shared among metal atoms.
Understand the concept of electronegativity: Electronegativity is the ability of an atom to attract electrons in a chemical bond. Different atoms have different electronegativities.
Differentiate between polar and nonpolar covalent bonds: In a nonpolar covalent bond, electrons are shared equally between atoms with similar electronegativities. In a polar covalent bond, electrons are shared unequally due to a difference in electronegativity between the bonded atoms.
Recognize the characteristics of a polar covalent bond: In a polar covalent bond, the atom with higher electronegativity attracts the shared electrons more strongly, creating a partial negative charge, while the other atom has a partial positive charge.
Conclude that a polar covalent bond is the type of bond where electrons are shared unevenly due to differences in electronegativity between the bonded atoms.
