This lesson focuses on ionic and covalent bonding concepts, exploring the nature of ionic bonds where oppositely charged ions attract, and how covalent bonds form through the sharing of electrons between non-metals. Students will learn to draw Lewis dot diagrams for carbon, hydrogen, and oxygen, and analyze scenarios involving the gain or loss of electrons. The objectives include applying electronegativity trends and understanding the law of conservation of mass as it relates to chemical reactions. Students will also be engaged in practice and exit ticket assessments.

POPQuiZ #1 Which statement explains why atoms bond? • Atoms bond to make new substances. • Atoms bond to become less chemically stable. • Atoms bond to change from a liquid to a solid. • Atoms bond to become more chemically stable.
Covalent Bonds Covalent bonds form between a non-metal & a non-metal
Covalent Bonds In a covalent bond atoms are connected by sharing electrons like best friends (forever!)
