Guiding Questions:
How do you decide what is true?
What you should learn:
Unit outline
- Using the periodic table
- Identify families (alkali metals, noble gases, etc)
- Give number of electrons, protons, neutrons of element
- Nomenclature and formulas (SOL Ch. 3 a, c)
- Distinguish between empirical, molecular, and structural formulas
- Name covalent compounds using the greek prefix system of mono, di, tri etc.
- Write chemical formulas given the name of a compound
- Choose the appropriate naming rules for a given chemical formula
- Learn the names and formulae of common anions and cations
- Write chemical formulas for ionic compounds given
- a. Name of compound or
- b. A pair of ions
- Identify polyatomic ions
- Classify compounds as being ionic or covalent.
- Name ionic compounds using stock system (Roman numerals)
- Lab Safety and Techniques (SOL Ch 1. a, b, c)
- Identify, locate, and know how to use laboratory safety equipment including aprons, goggles, gloves, fire extinguishers, fire blanket, safety shower, eye wash, broken glass container, and fume hood.
- Decide which safety and emergency procedures to follow in case of particular accidents including fires and hazardous material spills.
- Demonstrate the following basic lab techniques: using analytical balance (tare), obtaining chemicals without contamination, filtering, decanting, using chromatography, lighting gas burners.
- Demonstrate proper methods for carrying and moving chemicals and equipment.
- Experiment Design
- Design and perform experiments to test predictions
- Demonstrate precision (reproducibility) in measurement through the use of repeated trials
- Data Measurement and Manipulation (SOL Ch 1. f, g)
- Use dimension analysis to convert quantities from one metric unit to another, and also between metric and English units.
- Propagate errors in simple calculations
- Read a measurement from a graduated scale, stating measured digits plus the estimated digit.
- Report the degree of uncertainty of a measurement
- Determine the significant digits in a recorded measurement, and carry out mathematical operations using these measurements with answers rounded off to the correct number of significant digits.
- Report very large and very small numbers in scientific notation
- Perform mathematical operations on numbers in scientific notation
- Use data collected to calculate percent error.
