Chemical Bonding Quiz

What is the big idea of Chapter 6 in the learning material?

• Atoms form chemical bonds by sharing or transferring electrons.

• Atoms form chemical bonds by sharing protons.

• Atoms form chemical bonds by transferring neutrons.

• Atoms form chemical bonds by sharing photons.

Answer explanation

The correct choice highlights that atoms bond by sharing or transferring electrons, which is fundamental in chemistry. The other options incorrectly suggest protons, neutrons, or photons, which do not form chemical bonds.

What is a chemical bond?

• A mutual electrical attraction between the nuclei and valence electrons of different atoms

• A physical connection between atoms

• A magnetic force between atoms

• A gravitational pull between atoms

Answer explanation

A chemical bond is defined as a mutual electrical attraction between the nuclei and valence electrons of different atoms, which allows them to connect and form molecules. This distinguishes it from physical, magnetic, or gravitational forces.

How do atoms form compounds?

• By gaining, losing, or sharing electrons

• By splitting into smaller atoms

• By changing into different elements

• By increasing their size

Answer explanation

Atoms form compounds by gaining, losing, or sharing electrons. This process allows them to achieve stable electron configurations, leading to the formation of chemical bonds and thus creating compounds.

What results from the electrical attraction between cations and anions?

• Ionic bonding

• Covalent bonding

• Metallic bonding

• Hydrogen bonding

Answer explanation

Ionic bonding results from the electrical attraction between cations (positively charged ions) and anions (negatively charged ions). This interaction leads to the formation of ionic compounds, distinguishing it from other types of bonding.

What is covalent bonding?

• Sharing of electron pairs between two atoms

• Transfer of electrons from one atom to another

• Attraction between metal ions

• Formation of a crystal lattice

Answer explanation

Covalent bonding involves the sharing of electron pairs between two atoms, allowing them to achieve stability. This distinguishes it from ionic bonding, which involves the transfer of electrons.

What is the main difference between ionic and covalent bonding?

• Atoms transfer electrons in ionic bonding, while they share electron pairs in covalent bonding.

• Atoms share electron pairs in ionic bonding, while they transfer electrons in covalent bonding.

• Ionic bonding involves only nonmetals, while covalent bonding involves metals.

• Covalent bonding results in charged ions, while ionic bonding does not.

Answer explanation

The main difference is that in ionic bonding, atoms transfer electrons, leading to charged ions, while in covalent bonding, atoms share electron pairs, resulting in neutral molecules.

What is the electronegativity difference range for a polar-covalent bond?

• 0 to 0.3

• 0.3 to 1.7

• 1.7 to 3.3

• 3.3 to 5.0

Answer explanation

A polar-covalent bond occurs when the electronegativity difference between two atoms is between 0.3 and 1.7. This range indicates unequal sharing of electrons, resulting in partial charges.

Which type of bond is characterized by an unequal attraction for the shared electrons?

• Nonpolar-covalent bond

• Polar-covalent bond

• Ionic bond

• Metallic bond

Answer explanation

A polar-covalent bond occurs when two atoms share electrons unequally due to differences in electronegativity, leading to partial charges. This distinguishes it from nonpolar-covalent bonds, where electrons are shared equally.
