The questions cover the principles of the Periodic System of Elements, regularities of changes in chemical and physical properties of elements in groups and periods, their atomic and electronic characteristics. Special attention is paid to the relationship between the position of an element in the system and its chemical activity, as well as the ability to interpret the properties of elements and compounds based on their electronic configuration. The test is designed in accordance with educational standards and is suitable for independent preparation, consolidation of the studied material or testing knowledge.
