Unit 3 - Chemical Bonding - Chemistry Final Exam Review

Front

What is a chemical bond?

Back

A chemical bond is a lasting attraction between atoms, ions, or molecules that enables the formation of chemical compounds.

Front

What are the two main types of chemical bonds?

Back

The two main types of chemical bonds are ionic bonds and covalent bonds.

Front

What is an ionic bond?

Back

An ionic bond is formed when one atom transfers electrons to another atom, resulting in the formation of oppositely charged ions that attract each other.

Front

What is a covalent bond?

Back

A covalent bond is formed when two atoms share one or more pairs of electrons.
