P.S. 4: Periodic Table
- Use the periodic table of elements to obtain information about the atom of an element: symbol, atomic number, atomic mass, state of matter at room temperature, and number of outer energy level (valence electrons).
- Describe the organization of the periodic table in terms of: atomic number, metal, metalloids, non-metals, and groups/families vs periods.
- Categorize given elements as metal, non-metal, or metalloid.
- Given a chemical formula, identify the elements and the number of atoms of each which comprise the compound.
- Recognize that the number of electrons in the outermost energy level determines an element's chemical properties or chemical reactivity. Relate this to the octet and duet rules with regard to valence electrons.
- Predict what type of bond will likely form (ionic or covalent) when metals and non-metals combined chemically.
- Describe the difference between ionic and covalent bonding.
- Recognize that an atom's identity is related to the number of protons in its nucleus.
