This learning resource provides a detailed lesson on chemical bonding, covering ionic, covalent, and metallic bonds. It includes hands-on activities like mapping the periodic table, Lewis symbols, modeling bonding, and an experiment to differentiate ionic and covalent compounds based on properties. It also uniquely integrates Financial Education by associating the concept of electron transfer with the concept of donating, promoting financial literacy alongside scientific concepts. It follows an Understanding by Design (UbD) approach (Explore, Firm-up, Deepen, Transfer).
Objective
1. Identify the number of valence electrons of atoms using the periodic table.
2. Compare electronegativity and ionization energy of metals and non-metals.
* Illustrate how ionic bonds are formed through electron transfer.
* Illustrate how covalent bonds are formed through electron sharing.
* Model metallic bonds.
* Relate chemical bond types to compound properties.
* Explain the association of transferring/sharing electrons to the concept of donating
