Document Content and Description Below

OL Lab 3: Periodic Table of Elements: Get the table organized in time! Learning Objectives:  Describe the structure and organization of the periodic table  Classify elements of a family based... on their location in the periodic table  Distinguish metals from other element classes based on typical characteristics  Use the flame color test to identify metals based on their position in the periodic table  Explain valence electrons and oxidation state of a main group element to its position in the periodic table  Describe the main trends among groups and periods for atomic properties  Explain the causes on the atomic level for the main trends among groups and periods concerning atomic radii, ionization energy and electronegativity Introduction Light up the elements! In this simulation, you will learn all the fundamental ins and outs of the periodic table. Find out which elements have metallic characteristics, perform a flame test, and explore trends in atomic properties among the main groups and periods. A broken table The periodic table is an amazing tool for getting an overview of all the elements in existence, even the elements that only exist when we create them ourselves. But the table in this virtual lab is broken; some of the elements have fallen out, and it’s your mission to figure out where they belong by investigating their characteristics and properties. Flame color test and atomic properties To sort the first few elements in the table you can observe their flame colors. You may need to use your knowledge about element classes as well to get the full understanding. There are surprisingly many atomic properties for which trends can be observed via the periodic table. Moving on to the virtual holo-table, you will investigate these trends and deduct how they behave when you move within and between periods and groups of the table. You will need this knowledge to assign the most tricky fallen-out elements. Become the teacher At the end of the simulation, a special visitor will be coming by the lab, and she needs you to help her understand the basics of the periodic table. Part 1: Complete Labster Lab: Periodic Table of Elements: Get the table organized in time! Part 2: Report and Reflection Purpose: Describe in complete sentences and in your own words, the purpose of this experiment. How to predict chemical reactions to flames. The flame test is used to visually identify an unkn [Show More]
