CHEMISTRY SUMMER PACKET- 2017 Greetings Students! I would first like to congratulate you all for the successful completion of 2016-17 school year! I hope you take a bit of your precious summer time to prepare yourself to learn Chemistry, Sci-ence class for the upcoming school year. This summer packet consist of two sections and weigh 10% of your Q1 Chemistry grade. This packet is due on the first day of school. Section I: • Assignment #1: Elements in periodic table - 50 Points • Assignment #2: Metric and Unit System - 40 Points Section II: • Science and Engineering Fair Assignment - 40 Points Total - 130 Points Section I : Assignment #1 Introduction: You all know that Chemistry is our subject for the upcoming year. This subject has it’s own lan-guage. As you know every language has its own alphabets( 26 alphabets in English), Chemis-try has a long list of alphabets (known as elements) and you can see those well organized in a periodic table.

Here it is! Don’t get panic. You need to learn only a few of them ( first twenty) and the following list will give you the details: Check the list of alphabets (Elements)

# Name of Element Symbol of Element

1 Hydrogen H

2 Helium He

3 Lithium Li

4 Beryllium Be

5 Boron B

6 Carbon C

7 Nitrogen N

8 Oxygen O

9 Fluorine F

10 Neon Ne

11 Sodium Na

12 Magnesium Mg

13 Aluminum Al

14 Silicon Si

15 Phosphorus P

16 Sulfur S

17 Chlorine Cl

18 Argon Ar

19 Potassium K

20 Calcium Ca

All elements are to be written as shown on this list with a capital letter as the first letter and lowercase letter as the second letter. Do not write in all caps, or in cursive. You must know the spelling and symbol. Do not change the given order of elements. Memorization Tips: Elements/Symbols I am a huge fan of making analogy or mnemonics that help me to remember a concept . Please check the following link to get the mnemonics. https://www.mnemonic-device.com/chemistry/periodic-table/the-first-20-element-of-the-periodic-table/

Name of element Symbol of element Tips

Chlorine Cl “You Clean with chlorine!”

Helium He If you breathe in helium, you will laugh! He, He, He!

Sodium Na “Naw, I don’t want any so-dium!”

Oxygen O “Open your mouth wide to take in oxygen!”

Silicon Si Silly con!

Periodic Table of the Elements Fill in the blanks with the atomic symbols of the first 20 elements ( above listed ele-ments). (You do not need to add the atomic number, weight or name.) (1 point each for correct representation)

Assessment: ( for first twenty elements) Class quiz for 20 points based on first assignment. This will include following types of questions: • Identifying the name of elements of the provided symbol and vice versa. • Finding correct position of elements in periodic table. Assignment #2 ( Review of Math) There are a few topics you have learned in previous classes that you need to review. Those topics are as follows: • Review the metric system base units and their symbols.

• Know the metric prefixes, their values, and their symbols. • Be able to use dimensional analysis to complete conversion problems. SI Base Units

Quantity Unit name Unit abbreviation

Length meter m

Mass kilogram Kg

Temperature Kelvin K

Time Second s

SI Prefixes
