Bonding Quiz

What is ionic bonding?

• The formation of covalent bonds between atoms

• The transfer of electrons from one atom to another

• The attraction between two atoms due to their opposite charges

• The sharing of protons between atoms

How are ions formed in ionic bonding?

• By sharing electrons

• By both atoms losing electrons

• By both atoms gaining electrons

• By one atom losing electrons and another gaining electrons

Answer explanation

Ions are formed in ionic bonding when one atom loses electrons and another atom gains electrons.

What is covalent bonding?

• Atoms sharing pairs of positrons

• Atoms sharing pairs of protons

• Atoms sharing pairs of electrons

• Atoms sharing pairs of neutrons

Answer explanation

Covalent bonding is the sharing of pairs of electrons between atoms, which is the correct choice.

How are electrons shared in covalent bonding?

• Electrons are donated by one atom to another

• Electrons are not involved in covalent bonding

• Electrons are shared only within the same atom

• Electrons are shared between atoms.

Answer explanation

In covalent bonding, electrons are shared between atoms.

What is metallic bonding?

• Bonding between nonmetals

• Chemical bonding in plastics

• Chemical bonding in metals

• Bonding in covalent compounds

Answer explanation

Metallic bonding is the chemical bonding in metals, where positively charged metal ions are surrounded by a sea of delocalized electrons.

What properties do metals exhibit due to metallic bonding?

• Transparency, brittleness, and solubility

• Conductivity, malleability, and ductility

• Insulation, fragility, and rigidity

• Flexibility, hardness, and opacity

Answer explanation

Metals exhibit conductivity, malleability, and ductility due to metallic bonding.

What are covalent structures?

• Covalent structures are only found in metals

• A giant covalent structure is where a large number of atoms are joined by covalent bonds

• There are two kinds of covalent structures - small molecules, like water, and giant compounds, like diamonds.

• Covalent structures are formed by ionic bonds

Answer explanation

Covalent structures are formed when atoms share electrons to form covalent bonds.

Give an example of a covalent structure.

• Diamond

• Sodium chloride (NaCl)

• Iron (Fe)

• Molecule of water (H2O)

Answer explanation

A molecule of water (H2O) is an example of a covalent structure. Covalent bonds are formed when atoms share electrons, as in the case of water where two hydrogen atoms share electrons with one oxygen atom.

What are the differences between ionic and covalent bonding?

• Ionic bonding and covalent bonding are the same and can be used interchangeably.

• Ionic bonding involves the sharing of electrons between atoms, while covalent bonding involves the transfer of electrons from one atom to another.

• Ionic bonding and covalent bonding both involve the transfer of electrons from one atom to another.

• Ionic bonding involves the transfer of electrons from one atom to another, while covalent bonding involves the sharing of electrons between atoms.

Answer explanation

Ionic bonding involves electron transfer, while covalent bonding involves electron sharing.

In terms of electron sharing, how do ionic and covalent bonding differ?

• Ionic bonding and covalent bonding both involve the sharing of electrons.

• Ionic bonding involves the sharing of electrons, while covalent bonding involves the transfer of electrons.

• Ionic bonding and covalent bonding both involve the transfer of electrons.

• Ionic bonding involves the transfer of electrons, while covalent bonding involves the sharing of electrons.

Answer explanation

Ionic bonding involves electron transfer, while covalent bonding involves electron sharing.
