: Electronic configurations of elements in the first three periods.
According to official StatGrad 2025-2026 schedules , various diagnostic works are distributed throughout November, with some regions conducting specific chemistry assessments for the "Osh" (OGE) format around this timeframe. Overview of Diagnostic Content
: Known for posting StatGrad variants (e.g., HI2490101-04) with detailed solutions.
: Properties of Halogens, Oxygen, Sulfur, and Nitrogen groups. Typical Structure of the Assessment Most diagnostic works follow the OGE 2026 format :
: Covalent (polar/non-polar), ionic, and metallic bonds.
: Behavior of acids, bases, and salts in aqueous solutions.
: Electronic configurations of elements in the first three periods.
