Periodic+Classification

=GPS:=
 * (a) Use the Periodic Table to predict periodic trends including atomic radii, ionic radii, ionization energy, and electronegativity of various elements. [SC4-a]**
 * (b) Compare and contrast trends in the chemical and physical properties of elements and their placement on the Periodic Table. [SC4-b]**


 * LEARNING TARGETS: **
 * 1) I can describe the arrangement of elements in the modern periodic table.
 * 2) I can describe the relationship between electron configuration, atomic structure and the periodic table.
 * 3) I can classify the elements in to s,p,d,f blocks.
 * 4) I can locate element in the periodic table with the help of electron configuration.
 * 5) I can figure out valency and valence electrons of elements.
 * 6) I can define periodic properties and predict their trends across a period and down a group.
 * 7) I can predict trend in chemical and physical properties of elements in the periodic table.

=Task 3: Project - Trends in Physical Properties=

Properties of elements have a trend (change gradually) across a period or down a group in the periodic table. In this project you will explore this trend in three physical properties viz. Density, Melting point and Boiling point, using internet.

Download the template file (which is an excel sheet) CP Trends in P Properties Explore across the web, find the information and fill out the tables 1,3,5,7, and 9 in the order as you see on the excel sheet. The following websites may be helpful: [] [] How to plot graph in Excel Make sure that all the numeric values that you fill in the table have same units. Write down the units in the row heading or column heading (next to the word) and not with the numeric value. Tables 1,3,5,7, and 9 require data. With this data you will create a line graph (chart) in the excel and paste it in the space provided on the excel sheet. Fill out table 2 based on the graph-1 that you have created. Similarly, complete the tables 4,6,8,10 under each graph.

Before submission, check the rubric and make sure you score a 100. You will submit this excel sheet through [|www.edmodo.com], Create a username and password. If you already have a username and password, just join the group “Chem 15-16” using the group code y3f2au
 * PROJECT SUBMISSION**
 * Edmodo submission (Mandatory). **

After you are done completely, check with the rubric below and make sure you will score a 100. Click this link @http://www.freepdfconvert.com/ and convert your excel to PDF. Create a page in your wiki. **Name it Trends in Propertie**s. Upload this PDF file to this wiki page. Upload your excell sheet also.
 * PDF Submission on wiki.**
 * Attention:** Make sure you have only one sheet in your excel file. (Typically, when you create a new Excell file, it consists of 3 sheets. You need to delete the other two unused sheets)
