: Identifying types of bonds (ionic, covalent polar/non-polar, metallic, and hydrogen) and crystal lattice types. Typical Question Structure
: Arranging elements in order of increasing or decreasing properties (e.g., "Arrange Mg, Al, and Na by increasing metallic strength"). : Identifying types of bonds (ionic
: Remember that for main-group elements, the group number indicates the number of valence electrons. 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. : Identifying types of bonds (ionic
