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.

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.
