![]() Periodic table Introduction to the periodic. The short answer questions are conceptual and meant to see if the students are able to apply what they've learned in the unit. Here you can browse chemistry videos, articles, and exercises by topic. What is the expected trend in the ionic radius of M in these compounds Arrange these compounds in order of decreasing ionic radius of M. Element M is a metal that forms compounds of the type MX 2, MX 3, and MX 4, where X is a halogen. The vocabulary words can be found scattered throughout the different instructional worksheets from this unit. Using the periodic table, arrange Li, Ga, Ba, Cl, and Ni in order of increasing atomic radius. The study guide is divided into two sections: vocabulary and short answer questions. Periodic Table Worksheet Answer Key - Periodic Trend Worksheet Answers. Purpose: Once the instruction for the unit is completed, students can complete this study guide to aid in their preparation for a written test. J loses two electrons in a chemical reaction. Periodic Table Trends Study Guide View Worksheet Purpose: This is an activity meant to have students track and compare changes in electronegativity and atomic radius across a period and down a group.Įssential concepts: Periodic trends, group, period, electronegativity, atomic radius. This is a good aid for students who struggle with taking notes freehand. Each slide has a set of questions, fill-in-the-blanks, or tables that students fill in based on the information given. Purpose: This is a fill-in-the-blank style notes outline for students to complete as you complete the accompanying Powerpoint lecture.
