- Student should be able to indicate how an atom is bonding.(ionic or covalent)
- How do Ionic bonds form?
- Student will be able to used the ideas of Oxidation reduction to justify how an ionic bond is formed.
- Student will be able to determine if a substance is using ionic bonding.
- Students will be able to write ionic formulas and names for specific ionic compounds.
- Students should be able to draw a representation of an ionic crystal and relate that drawing to the chemical formula of that substance.
- What are the properties of ionic compounds?
- A student should be able to determine how ionic charge and ionic radii affects the Melting point of an ionic compound. (Coulombs law)
