Covalent bonds are formed when atoms share electrons to achieve a stable electron configuration, typically an octet. The sharing of electrons leads to the formation of molecules.
1. Which of the following best describes a covalent bond?
Transfer of electrons between atoms
Sharing of electrons between atoms
Attraction between oppositely charged ions
Formation of a metallic lattice
2. What type of bond is formed between two oxygen atoms in an O₂ molecule?
Single covalent bond
Double covalent bond
Triple covalent bond
Ionic bond
1. In a covalent bond, electrons are between atoms.
2. A molecule with a single covalent bond forms when each atom contributes electron to the shared pair.
3. The prefix 'di-' in a covalent compound name indicates atoms of that element.
1. Explain the difference between a polar and a nonpolar covalent bond.
2. Write the chemical formula for dinitrogen tetroxide.
Match the covalent compound name with its chemical formula.
1. Carbon dioxide
a. N₂O
2. Water
b. CO₂
3. Ammonia
c. CH₄
4. Methane
d. H₂O
5. Dinitrogen monoxide
e. NH₃
1. Covalent bonds typically form between a metal and a nonmetal.
True
False
2. The subscript in a chemical formula indicates the number of atoms of that element.
True
False
