Read each question carefully and answer to the best of your ability.
1. What property of an atom determines its ability to attract electrons in a chemical bond?
Ionization energy
Electron affinity
Electronegativity
Atomic radius
2. A bond between two atoms with a large difference in electronegativity will most likely be:
Nonpolar covalent
Polar covalent
Ionic
Metallic
1. In a nonpolar covalent bond, electrons are shared equally between two atoms.
True
False
2. Water (H2O) is a nonpolar molecule because of its symmetrical structure.
True
False
1. The measure of an atom's ability to attract electrons in a chemical bond is called .
2. A bond formed between two atoms with a small electronegativity difference (0.0-0.4) is generally considered to be a bond.
3. In a covalent bond, electrons are shared unequally, creating partial positive and negative charges.
1. Explain the difference between a polar covalent bond and a nonpolar covalent bond.
2. Give an example of a molecule with polar bonds but is a nonpolar molecule overall. Explain why.
