Summer Assignment Honors Chemistry Mrs. Peabody Hi everyone -­‐ welcome to Honors Chemistry! To jump-­‐start our year, you will have a memorization summer assignment. Even though there may not seem much to it, don’t leave it until the end of summer -­‐ there will be a test on the material on the day you come back to school! Here it is: (1) Elements: Memorize the element symbols and names for elements # 1 -­‐ 20, 24 – 30, 33, 35 – 38, 46 -­‐ 48, 50, 53 – 56, 74, 78 – 80, 82, 86 – 88, 92, and 94 -­‐ an even fifty. Use the 3 attached Periodic Tables to help. One has only the symbols; the other two have both the symbols and names. You do not need to memorize atomic or mass numbers or positions of the elements on the table. As we go through the school year, you will be assigned others to also learn. You will be responsible for knowing these symbols and names throughout the school year – sort of like knowing a basic alphabet in preparation for learning a new language; in this case, the alphabet is the chemical symbols and the language is chemistry! (2) SI Metrics units: (a) Memorize the seven SI base units of measure, their symbols, and the property for which each unit is used. For instance, one of the base units is the meter. Its abbreviation is m. The property it is used to measure is length or distance. You may start here: http://physics.nist.gov/cuu/Units/units.html (Table 1). (b) Memorize the prefixes Mega-­‐, kilo-­‐, deci-­‐, centi-­‐, milli-­‐, micro-­‐, nano-­‐, and pico-­‐, their abbreviations, and their meanings. (For instance, milli-­‐ has m as its abbreviation, and means x10-­‐3.) You may start here: http://physics.nist.gov/cuu/Units/prefixes.html Studies of chemistry, as is true of all sciences, are based on careful observation. In the case of chemistry and other physical sciences, the observations are often quantitative in nature and involve measurement of different properties. Measurements are used in calculations throughout the study of chemistry, as it is based heavily on mathematical relationships. We will begin our study of chemistry this September with a measurements topic, which will involve using the SI system of measures, Scientific exponential notation, conversions among units of measure, and error and precision in measurements. Come prepared by having completed the summer memory assignment given above! [3 periodic tables follow] Periodic Table of the Elements
