Understanding Ionic and Covalent Bonds Quiz

What is an ionic bond?

• A bond formed by the sharing of electrons between two atoms.

• A bond formed by the transfer of electrons from one atom to another.

• A bond that only occurs between metal atoms.

• A bond that involves the mutual attraction between oppositely charged ions.

What is a covalent bond?

• A bond formed by the sharing of electrons between two nonmetal atoms.

• A bond formed between a metal and a nonmetal.

• A bond that involves the transfer of electrons.

• A bond that only occurs in ionic compounds.

Which of the following best describes the formation of an ionic bond?

• Two atoms share their valence electrons equally.

• An atom donates its valence electron to another atom, creating ions that attract each other.

• Two atoms exchange neutrons to achieve stability.

• Electrons are shared unequally between two atoms.

What is a key difference between ionic and covalent bonds?

• Ionic bonds occur only in organic compounds, while covalent bonds occur in inorganic compounds.

• Ionic bonds involve the sharing of electrons, while covalent bonds involve the transfer of electrons.

• Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

• Covalent bonds can only form between two metals, while ionic bonds can form between a metal and a nonmetal.

Which of the following is NOT a property of covalent compounds?

• Low melting points.

• High melting points.

• Poor conductivity in water.

• Tend to be gases, liquids, or soft solids at room temperature.

How do ionic bonds affect the physical properties of ionic compounds?

• They make ionic compounds highly volatile.

• They give ionic compounds high melting and boiling points due to strong attractions between ions.

• They result in ionic compounds being soft and malleable.

• They cause ionic compounds to have low solubility in water.

In a covalent bond, what happens to the valence electrons?

• They are transferred from one atom to another.

• They are shared between atoms.

• They are lost to the surrounding environment.

• They are used to form ionic bonds.

Why do ionic compounds conduct electricity in a liquid state but not in a solid state?

• In a liquid state, ions are free to move and carry charge, whereas in a solid state, ions are fixed in place.

• Ionic compounds always conduct electricity regardless of their state.

• The ions in ionic compounds are neutralized in a solid state.

• Ionic compounds do not conduct electricity in either state.

• A metal and a nonmetal.

• A metalloid and a nonmetal.
