periodic trends on the periodic table chemistry 11 activity

Ryan Seacrest = Nucleus Mouthwash = Effective Nuclear Charge Ladies = Electronsġ6 ROADBLOCK #3 Each periodic trend is really its own separate concept. ROADBLOCK #1 Visualizing attractive and repulsive forces between nucleus and electrons ROADBLOCK #2 Understanding that the nucleus can have an ‘effective nuclear charge’ and that inner-level electrons can shield the nucleus from outer-level electronsġ3 Ryan Seacrest shows Effective Nuclear Charge with his smile!ġ4 The Solution to Misconceptions 1 and 2: The Analogy with Atomic Radius Teachers have a two-fold problem when it comes to teaching periodic trends: Explaining (as opposed to simply memorizing) the subatomic basis for all five trends Atomic Radius (Ionic Radius) Ionization Energy Electron Affinity Electronegativity Reactivity of Metals and Non-Metals Looking for ways to help students retain and review the knowledge of Periodic Trends The Concept Atomic Radius Ionization Energy Effective Nuclear Charge PERIODIC TRENDS Electron Affinity Shielding Effect Electronegativity Reactivity The placement of the concept of the unit fits appropriately in the context of the chapter Both McGraw-Hill and Nelson texts place the concept in the following way: Atoms, Elements and the Periodic Table Periodic Trends (Involving the Sizes and Energy Levels of Atoms) Classifying Chemical Compounds (Ionic vs.

A1.6 Compile accurate data from laboratory and other sources, and organize and record the data using appropriate formats, including tables, charts, graphs, and/or diagrams A1.10 Draw conclusions based on inquiry results and research findings, and justify their conclusions with reference to scientific knowledge.ĥ Curriculum Expectations (Ontario Ministry of Education)ī1.1 Analyse, on the basis of research, the properties of a commonly used but potentially harmful chemical substance and how that substance affects the environment, and propose ways to lessen the harmfulness of the substance or identify alternative substances that could be used for the same purpose. SPECIFIC EXPECTATIONS A1.5 Conduct inquiries, controlling relevant variables, adapting or extending procedures as required, and using appropriate materials and equipment safely, accurately, and effectively, to collect observation and data.
