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

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

: Remember that for main-group elements, the group number indicates the number of valence electrons. : When an atom becomes a cation (positive

Most versions of this work are divided into two variants, each containing:

: Electronegativity increases toward Fluorine (up and to the right), while atomic radius increases toward Francium (down and to the left). Most versions of this work are divided into

The (Verification Work No. 1) in O.S. Gabrielyan's 11th-grade chemistry textbook (Basic Level) typically focuses on the fundamental structure of the atom and the Periodic Law. Core Topics Covered

: Writing the full and abbreviated electronic formulas for specific elements (e.g., Phosphorus or Calcium). Typical Question Structure

: Identifying types of bonds (ionic, covalent polar/non-polar, metallic, and hydrogen) and crystal lattice types. Typical Question Structure
