Bonding Review Quiz

Why does an ion have a charge?

• There are different numbers of protons and neutrons.
• There are different numbers of neutrons and electrons.
• There are different numbers of protons and electrons.
• There are different numbers for atomic mass and atomic number.

How do ionic bonds form?

• Atoms share electrons to fill their valence shell.
• Atoms gain or lose electrons to fill their valence shell.
• Atoms donate electrons to a "sea" of electrons.

Which statement about covalent bonds is true?

• Covalent bonds are weaker because they are just the best!

• Covalent bonds are generally stronger than ionic because they have positive and negative charged elements involved.

• Covalent bonds are usually weaker than ionic bonds because they do not have positive and negative charged elements, instead they share electrons to fill the outer shell.

Which of these BEST describes why an ionic compound is a good conductor of electricity while a covalent compound is a poor conductor of electricity.

• Ionic compounds form charged particles in solution, and electricity will only flow if charged particles are present.

• Covalent compounds form charged molecules in solution, and I mean covalent compounds are just that.

The illustration depicts the formation of an ionic chemical bond between lithium and fluorine atoms. Why is the resulting compound more stable than the individual atoms?

• The shared electron from lithium to fluorine provides each atom with an empty electron shell.

• The transferred electron from lithium to fluorine provides each atom with a full outer energy level/ electron shell.

• The transfer of electrons from lithium to fluorine provides each atom with an empty electron shell.
