TEKS Reflection/Matter and Energy_Properties of Atoms

Using the information provided from the 9 weeks assessments. Use pencil and label to record progress. Common note mistakes are: • Misidentifying an atom based on subatomic particle data • Misidentifying the charge of the nucleus and the electron cloud • Not recognizing subatomic particles, charges, location, or how to use an element symbol to determine these values • Confusing mass number and atomic mass on element symbols • Struggling to identify reactivity based on valence electrons • Not recognizing the majority of the mass of an atom is in the nucleus and that the majority of the volume is in the electron cloud • Not understanding that groups are vertical and periods are horizontal • Not recognizing the representative groups, metals, nonmetals, metalloids, and patterns of valence electrons • Struggling to identify the location of elements on the Periodic Table based on characteristics
