Chemistry for the Week! Monday: Atomic Structure Be able to identify and label the location and charge of subatomic particles. Be able to identify the number and location of subatomic particles for the first twenty elements on the periodic table. HW: For Monday night’s homework, draw (Bohr diagrams) what the atoms look like (example below) for ten different elements (1-20). For each one, write out a sample answer like the one below. For example, given the information for nitrogen, you should be able to label a diagram AND identify how many protons, neutrons, and electrons a nitrogen atom contains. Example answer: Nitrogen has 7 protons and 7 electrons located in the nucleus. I know this because the atomic number is 7. Nitrogen has 7 neutrons, because the mass in the nucleus is 14 – 7 protons = 7 neutrons. We practiced this in class with cereal and in your notebooks the APE MAN page located under your periodic table, breaks this down. Also, be able to look at a diagram and tell what element it is: Some websites to use: http://education.jlab.org/elementmath/ http://education.jlab.org/elementflashcards/ (This one lets you select WHICH elements to learn! Click the More Options button to select the 25 you need to know!) Tuesday: Vocabulary HW: Make sure you could teach someone what each of the following words means. Try it out on a family member! Draw a picture, describe, locate, etc. neutrons electrons Valence electrons Atomic number Metals Non-metals groups protons malleability Wednesday: Periodic Table atomic mass elements atoms metalloids periods families reactivity density ductility Explain some of the trends on the periodic table. (Mass, reactivity, metals, non-metals, metalloids). Given period/family information, locate an element. Describe the information provided in each element box. HW: 1. For ten elements (1-20), identify the family and period location for each, and what knowing that tells you. Create a table for your information. 2. Reread the History of the Periodic Table homework assignment. 3. Review the 25 elements/symbols you had to know for the last two quizzes. Make sure you know them! Element Nitrogen Family 15 Period Information 2 Non-metal with 2 electron shells; 5 valence electrons Continue with 10 of your choice from 1-20. Thursday: Chemistry of a Cookie, read and answer questions.
