C2.5 investigate and compare the chemical prop- erties (e.g., combustibility, reaction with water) of representative elements within groups in the periodic table families of elements (e.g., Mg and Ca; N and P) [PR, AI]
C2.6 construct and draw models of simple mole- cules (e.g., H2, NH3, CO2, CH4) [PR, C]
C2.7 conduct chemical tests to identify common gases (e.g., oxygen, hydrogen, carbon dioxide) on the basis of their chemical properties, and record their observations [PR, AI, C]
C3. Understanding Basic Concepts
By the end of this course, students will:
C3.1 identify the characteristics of neutrons, pro- tons, and electrons, including charge, location, and relative mass
C3.2 describe the characteristics that distinguish elements from compounds (e.g., elements are pure substances made up of only one kind of atom; compounds are pure substances made up of more than one kind of element)
C3.3 identify general features of the periodic table (e.g., metals appear on the left of the periodic table; non-metals appear on the right; elements within the same group have similar properties)
C3.4 explain the relationships between the proper- ties of elements and their position in the periodic table (e.g., with reference to atomic structure, group, and period)
C3.5 describe the characteristic physical and chemical properties of common elements (e.g., density, texture, odour, combustibility, solubil- ity, ability to conduct or absorb heat)
C3.6 use symbols and chemical formulae to repre- sent common elements and simple compounds (e.g., C, O, H, H2O, CO2)
C3.7 identify the elements and compounds in common household products (e.g., hydrogen peroxide, lye, salt)
