b. Introduction to Atoms and Elements

Transcription

1 Welcome to Honors Chemistry at ACHS! Honors Chemistry is for the student who desires a more in-depth study of science that will incorporate various aspects of science and math with an emphasis on both mastery and critical thinking/application skills. This is a fastpaced course that requires much outside classroom preparation. A summer assignment is essential to a good foundation as we incorporate more reading across the curriculum and giving all students an opportunity to learn more about what chemistry prior to starting the course! This class requires a strong work ethic and the ability to work independently. Let s start strong by getting ahead-start! Make sure that you complete all parts of the summer assignment! The assignment will be due on the first day of the school year. Do not wait until the end of the summer to start working! Please Print this entire packet out and bring with you on the first day of school You MUST complete ALL sections and be ready for the 1 st day of school 1. Memorize your polyatomic formulas listed on page 3 Quiz on polyatomic ions second week of school 2. Complete the element name activity on page Study the student safety contract on page 5 be ready for a quiz the first week of school. 4. Memorize the required elements on page 6 expect a quiz the second day of school over the required elements you should know the symbol and correct spelling of the element You should also print out part I of the summer assignment. Print it two sided and cut out and you have a great set of study cards! 5. Watch video notes listed and take Cornell style notes on the following Khan Academy videos: a. Introduction to the Atom b. Introduction to Atoms and Elements 6. Purchase your chemistry supplies and bring them with you the first day of your chemistry class. Student Supplies Chemistry Student Supplies One 5-Subject Mead/Five star HEAVY DUTY (plastic cover) -College ruled (Do NOT get wide ruled). It is extremely important that students purchase the : Mead/Five star HEAVY DUTY (plastic cover) 5 subject Notebook College ruled These are the only notebooks that are the correct size for the Chemistry Interactive Learning Log (C.I.L.L) that you will be making this year Pen, pencil, and highlighters/color pencils or markers that do not bleed through paper Post it tabs to section of units chemistry notebook. Stapler and staples/ or double sided tape roller Scientific Calculator - TI-30Xa recommended (about $10) - if students already have a scientific/and or graphing calculator they do not need to purchase another one. 2 roll(s) of paper towels (very important!) 2 bottles of Clorox/chlorine wipes (very important!) Chemistry Class Supplies: LAST NAME A - K 1 box of Kleenex or 1 Bottle of Hand sanitizer or hand soap LAST NAME L - P glue sticks LAST NAME Q Z or galloon or quart size zip lock backs 1

2 7. $6 per student to cover Special Supplies In addition, during certain units we will complete labs using perishable items that must be purchased close to lab/activity date. The $6.00 collected from students will be used to purchase these items, please bring your $$$ you to be collected at the beginning of the school year. Popcorn (percent Water in popcorn Lab) Graham crackers, Hershey bars, marshmallows (Limiting reactant activity) Cream, sugar, vanilla, ice cream salt (freezing point depression lab) Cupcakes, frosting, mini M&Ms, frosting food color (periodic table of cupcakes) Mole day celebration 2

3 POLYATOMIC IONS Please study and memorize Polyatomic ions are groups of multiple atoms that have a charge (positive or negative). The symbols shown below tell you what elements are in the ion, how many atoms of each, and the charge. For example: NH 4 +1 contains a nitrogen atom, four hydrogen atoms and the entire group has a charge of +1. Memory Hint: If you have two ions with similar names and the only difference is the number of oxygen atoms in your ion: -ite means smaller number of O -ate means larger number of O Hypo- (smallest) and Per- (largest) are used if there are four ions with similar names and different numbers of oxygen. ION NAME ION NAME NH41+ ClO 1- ClO21- ClO31- ClO41- CN1- OH1- IO31- NO31- ammonium hypochlorite chlorite chlorate perchlorate cyanide hydroxide iodate nitrate NO21- MnO41- CO32- nitrite permanganate carbonate O22- peroxide SO42- SO32- PO43- CH3COO1- sulfate sulfite phosphate acetate 3

5 Chemistry Safety Contract for (print name) The following is a safety contract that outlines the rules for the chemistry laboratory. Two copies of the contract are provided; one copy must be signed both by you and your parent or guardian. The second copy is to be kept in your science notebook as a constant reminder of the safety rules. 1. When working in the laboratory, you must wear your safety goggles at ALL times. There are NO exceptions to this rule. 2. Students are not allowed in the chemical stockroom under any circumstances. 3. Do not eat food, drink beverages, or chew gum in the laboratory. Never use laboratory glassware as containers for food or beverages. 4. Know the locations and operating procedures of all safety equipment (including the first aid kit, eyewash station, safety shower, fire extinguisher, and fire blanket). Know where the fire alarm and the exits are located. 5. Follow all verbal and written instructions carefully. If you do not understand an instruction, ask your teacher before proceeding. 6. When first entering a science room, do not touch any equipment, chemicals, or other materials in the laboratory area until you are asked to do so. 7. Perform only those experiments authorized by your teacher. Unauthorized experiments are strictly prohibited. 8. Keep your work area clean at all times. Spills should be wiped up immediately. 9. Keep hands away from face, eyes, mouth, and body while using chemicals. Wash your hands with soap and water after performing all experiments. 10. If a chemical should splash into your eyes, immediately flush with running water from the eyewash station for at least 20 minutes. Notify your teacher immediately. 11. All chemicals in the laboratory are to be considered dangerous. Do not touch, taste, or smell any chemicals unless specifically instructed to do so. 12. Above all, conduct yourself in a responsible manner at all times in the laboratory. If you have a question, make sure to ask your teacher. Questions: a. Do you wear contact lenses? b. Are you color blind? c. Do you have any allergies? If so, please list below: I have read and agree to follow all of the safety rules set forth in this contract. I realize that I must obey these rules to insure my own safety, and that of my fellow students and instructors. I am aware that any violation of this safety contract that results in unsafe conduct may result in removal from the laboratory, a failing grade, and/or dismissal from the course. student signature parent/guardian signature date date 5
