: Arranging elements in order of increasing or decreasing properties (e.g., "Arrange Mg, Al, and Na by increasing metallic strength").

: Multiple-choice items focusing on identifying isotopes or determining the number of neutrons/protons. : Arranging elements in order of increasing or

: When an atom becomes a cation (positive ion), it loses electrons; an anion (negative ion) gains them. it loses electrons

: Distribution of electrons in energy levels, s/p/d orbitals, and electron configurations for atoms and ions. such as changes in atomic radius

: Trends in the Periodic Table, such as changes in atomic radius, electronegativity, and metallic/non-metallic properties across periods and groups.
