Scholars Chemistry Summer Assignment Welcome to Chemistry! In an effort to assist you towards preparing for your chemistry class, please introduce yourself to the following concepts. The assignments were designed to be straightforward, simple, easy to locate and easy to comprehend. You will be able to locate most solutions in your textbook or online. Most assignments were designed to prepare you for key ideas. Other assignments were designed to broaden your appreciation of chemistry and the role it plays in everyday life. The assignment is due the first day of class. You will be tested on this information the second day of class. Please make a copy of the assignment for yourself. Please do not hesitate to contact me at kalessi@bishopgorman.org. I will check my email biweekly (every other week). Element Names & Symbols (7.5 pts) Complete the chart below (spelling counts) and tape into your assignment. It is highly recommended that you spend a portion of your summer learning these names and symbols. Symbol Name H Na Potassium Mg Calcium Iron Ni Cu Silver Gold Zn Hg Aluminum C Silicon Symbol Name Tin Pb N P Oxygen Sulfur F Cl Bromine Iodine He Ne Argon Xenon Radon
Elements Facts (12 pts) Use your birth day to determine the atomic number of the element you will research. For example, if you were born on December 8 th, you will research Atomic Number 8, which is OXYGEN. On the Internet, open either http://www.chemicalelements.com/ or http://www-tech.mit.edu/chemicool/. Click on related links on the Web site to find more information about your element. Find the following information about your element: Atomic symbol Atomic number Atomic mass Electron configuration Number of neutrons Melting point Boiling point Color Date of discovery Draw its atomic structure Isotopes Uses for your element This element is obtained from Create a poster (11x14) of the information found on the element. The poster should contain all of the information that was found on the Internet and any additional information you would like to include. The poster should be very colorful, very creative and very informative. Note: These posters will be used as classroom artwork.
Periodic Table (6 pts) Obtain a copy of the Periodic Table from the Internet. The Periodic Table will become a very close companion during the school year. Locate metals, nonmetals & metalloids on the Periodic Table. Please shade in the sections of the Periodic Table, preferably in the colors indicated: a) metals (red), b) nonmetals (blue), c) metalloids (yellow). Next define the terms: a) metal, b) nonmetal, c) metalloid Locate Groups & Periods on the Periodic Table. Indicate the direction of Groups via an arrow drawn on your Periodic Table. Indicate the direction of Periods via an arrow drawn on your Periodic Table. Remember to label your arrows. Indicate the following Groups by writing their name in the appropriate location on your Periodic Table: a) halogens, b) Noble gases, c) alkali metals, d) alkaline earth metals Atoms (4.5 pts) Complete the chart below. Subatomic Particle Location Charge Relative Mass Proton Neutron Electron Science Is All Around Us (5 pts) Locate two articles through everyday encounters (i.e., newspaper, magazine). Do not do Internet searches of terms. The idea is for you to realize that science is around you at all times, even without you searching. For example, do you recall recently hearing about the following: cadmium in children s jewelry? high fructose corn syrup? effects of ash on jet engines? mercury in tuna? Write four or more sentences offering your opinions and comments on each topic you encountered, include why the topic caught your interest. Be sure to include a copy of any article. If you find this fun, then please keep going and create a journal. I enjoy reading other people s comments about science.
Introduction to Chemistry Questions (25 pts) Answer the following. Full sentences are not needed, instead imply the question in the answer. For example, do not answer, gains electrons, instead write Li gains electrons. 1) What is the chemical formula for ozone? 2) What elements are found in CFCs? 3) What are the properties of matter? 4) How is mass different from weight? 5) Determine which field of chemistry is most likely to do the following: a) study the compounds containing carbon b) study the effect of mercury in living organisms 6) Why is the scientific method used? 7) How is qualitative data different from quantitative data? Provide an example of each type. 8) How does a hypothesis become a theory? 9) Define the term isotope. 10) What are the three isotopes of hydrogen? 11) What does the word alkali mean? 12) List some properties of the alkali metals. 13) List one use for five the following: a) Lithium b) Sodium c) Potassium d) Calcium 14) List one use for each member of the Halogen family. 15) List one use for each member of the Noble Gas family. e) Magnesium f) Nitrogen g) Phosphorus 16) Where are the transition metals located in the periodic table? 17) Define the term diatomic. Next, list the elements that are diatomic (i.e., H 2 ) 18) Define the term cation. Give an example of a cation. 19) Define the term anion. Give an example of an anion. 20) Define the term enthalpy. 21) Define the term entropy.
Suggestions for Preparing 1) Chemistry is more like a math class, less like a biology class. There is a lot of math involved (your calculator will also become a constant companion). 2) Chemistry involves more understanding of concepts and applying them, less memorization of terms. 3) It would be great if you could come into class knowing about significant figures, rounding, and scientific notation. We will take some time at the start of the school year to cover these concepts, as they are important to your future success in any science class. 4) The following site has an excellent tutorial on significant figures: http://www.chem.sc.edu/faculty/morgan/resources/sigfigs/index.html. 5) Refer to your calculator s handbook (or online reference) for assistance with entering scientific notation (i.e., 6.02 x 10 23 ) into your calculator. 6) Please start reading your textbook (for fun )
