Ionic vs Covalent Naming & Formula Writing

What is the naming convention for ionic compounds?

• Ionic compounds are named by stating the anion first followed by the cation.

• Ionic compounds are named by using the cation's name only.

• Ionic compounds are named by stating the cation first followed by the anion, with the anion's name modified to end in '-ide' for simple ions.

• Ionic compounds are named by combining the names of the cation and anion without any modifications.

What is the difference between ionic and covalent bonds?

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