Appendix I State Standards
Virginia Standards of Learning (SOLs) for Chemistry
CH.1The student will investigate and understand that experiments in which variables are measured, analyzed, and evaluated produce observations and verifiable data. Key concepts include
- designated laboratory techniques;
- safe use of chemicals and equipment;
- proper response to emergency situations;
- manipulation of multiple variables, using repeated trials;
- accurate recording, organization, and analysis of data through repeated trials;
- mathematical and procedural error analysis;
- mathematical manipulations (SI units, scientific notation, linear equations, graphing, ratio and proportion, significant digits, dimensional analysis);
- use of appropriate technology including computers, graphing calculators, and probeware, for gathering data and communicating results; and
- construction and defense of a scientific viewpoint (the nature of science).
CH.2The student will investigate and understand that the placement of elements on the periodic table is a function of their atomic structure. The periodic table is a tool used for the investigations of
- average atomic mass, mass number, and atomic number;
- isotopes, half lives, and radioactive decay;
- mass and charge characteristics of subatomic particles;
- families or groups;
- series and periods;
- trends including atomic radii, electronegativity, shielding effect, and ionization energy;
- electron configurations, valence electrons, and oxidation numbers;
- chemical and physical properties; and
- historical and quantum models.
