B2.2 analyse data related to the properties of elements within a period (e.g., ionization energy, atomic radius) to identify general trends in the periodic table [AI]
B2.3 use an inquiry process to investigate the chemical reactions of elements (e.g., metals, non-metals) with other substances (e.g., oxygen, acids, water), and produce an activity series using the resulting data [PR, AI]
B2.4 draw Lewis structures to represent the bonds in ionic and molecular compounds [PR, C]
B2.5 predict the nature of a bond (e.g., non-polar covalent, polar covalent, ionic), using electro- negativity values of atoms [AI]
B2.6 build molecular models, and write structural formulae, for molecular compounds containing single and multiple bonds (e.g., CO2, H2O, C2H4), and for ionic crystalline structures (e.g., NaCl) [PR, AI, C]
B2.7 write chemical formulae of binary and polyatomic compounds, including those with multiple valences, and name the compounds using the International Union of Pure and Applied Chemistry (IUPAC) nomenclature system [AI, C]
B. Understanding Basic Concepts
By the end of this course, students will:
B3.1 explain the relationship between the atomic number and the mass number of an element, and the difference between isotopes and radio- isotopes of an element
B3.2 explain the relationship between isotopic abundance of an element’s isotopes and the relative atomic mass of the element
B3.3 state the periodic law, and explain how patterns in the electron arrangement and forces in atoms result in periodic trends (e.g., in atomic radius, ionization energy, electron affinity, electronegativity) in the periodic table
B3.4 explain the differences between the forma- tion of ionic bonds and the formation of covalent bonds
B3.5 compare and contrast the physical properties of ionic and molecular compounds (e.g., NaCl and CH4; NaOH and H2O)
