This assessment evaluates your understanding of the early chapters, specifically:
: Writing the full and abbreviated electronic formulas for specific elements (e.g., Phosphorus or Calcium).
: Remember that for main-group elements, the group number indicates the number of valence electrons. This assessment evaluates your understanding of the early
: Multiple-choice items focusing on identifying isotopes or determining the number of neutrons/protons.
: Trends in the Periodic Table, such as changes in atomic radius, electronegativity, and metallic/non-metallic properties across periods and groups. such as changes in atomic radius
: Distribution of electrons in energy levels, s/p/d orbitals, and electron configurations for atoms and ions.
Most versions of this work are divided into two variants, each containing: it loses electrons
: When an atom becomes a cation (positive ion), it loses electrons; an anion (negative ion) gains them.
