Expectations B22 B33 17 Periodic Trends and Atomic Properties Learning Goals By the end of this class I will Describe and explain periodic trends related to Atomic radii Ionic radii. Molecular Geometry. Ch. 6 Sections 1-4 Review. In general, what determines whether atoms will form chemical bonds?. Atoms will form a chemical bond if their potential energy is lowered in doing so.. Describe the difference between ionic and covalent bonding.. Introduction to Chemical Bonding. Introduction to Chemical Bonding. Objectives:. Define . chemical bond.. Explain why most atoms form chemical bonds.. Describe ionic and covalent bonding.. Explain why most chemical bonding is neither purely covalent nor purely ionic.. Molecular Shapes. VSEPR Theory. From a correct Lewis structure, we can get to the 3-D shape using this theory.. VSEPR stands for . v. alence . s. hell . e. lectron . p. air . r. epulsion.. The theory is based on the idea that e- pairs want to get as far away from each other as possible!. . and Structure. IB Chemistry. Topic 4. . Bond - A force that holds . atoms . together and . makes . them . function as a . unit.. 4.1 Ionic Bonding. An . ion. is a charged particle. Ions form from atoms or from groups of atoms by . EQ: How are changes in matter related to changes . in energy?. Changes in Matter. You are at the beach. You built a sandcastle!. You notice storm clouds gathering in the distance.. You are sad : (. You know your sandcastle is about to go bye-bye.. Higher Supported Study - Week 2 . Key Areas – Periodic Trends . The trends in . covalent radius . across periods and down groups.. The trends in . ionisation energies . across periods and down groups. . What is matter? . Matter: . Anything that . hass. mass and volume . Matter can be measured in these ways: . Volume: amount of space that matter takes up . Mass: a measure of matter’s inertia (more mass = greater inertia) . June 12, 2012. Todd Hale. SVP, Consumer & Shopper Insights. Table of Contents. 2.

Students will examine the scientific view of the nature of matter. . e. Distinguish between changes in matter as physical (i.e., physical change) or chemical (development of a gas, formation of precipitate, and change in color). . Grade 5. Physical and Chemical Changes in Matter. Department of Science. Physical . and Chemical Changes in Matter. Benchmarks. SC.5.P.9.1 Investigate and describe that many physical and chemical changes are affected by temperature.. EQ: How are changes in matter related to changes . in energy?. Changes in Matter. You are at the beach. You built a sandcastle!. You notice storm clouds gathering in the distance.. You are sad : (. You know your sandcastle is about to go bye-bye.. 2-1 Energy . 2-2 Temperature . 2-3 Matter . 2-4 Elements and Compounds . 2-5 Mixtures . 2-1 Energy. Name 3 basic forms of nrg. State the law of conservation of nrg. Need for nrg. Heat water for cooking, bathing, etc.. Describing Matter. Extensive Properties: depend on amount of matter in a sample. Mass: amount of matter. Volume: space occupied. Intensive Properties: depend on type of matter, not amount. Density: mass/volume. Chapter 1 Matter on the Atomic Scale Chemistry The science of matter and the transformations it can undergo. Consider the anticancer drug Taxol ® . Why should you study it? It helps us understand our surroundings and the way we function.
