![]() ![]() ![]() Going to be away No problem Leave this activity (and answer keys) with a substitute teacher THIS RESOURCE INCLUDES: - Informational Text - Periodic Table (2 versions) Version 1. These questions can be used as a self-assessment, or can be collected and assessed. (In the modern periodic table, a group or family corresponds to one vertical column. Once the periodic table is colored, students can answer the 15 questions. The periodic table allows chemists a shortcut by arranging typical elements according to their properties and putting the others into groups or families with similar chemical characteristics. Were it not for the simplification provided by this chart, students of chemistry would need to learn the properties of all 118 known elements. ![]() Use the Periodic Table of Elements to predict the chemical behavior of an element. Compare the relative reactivity of metals and. Describe metals, nonmetals, and metalloids 3. Identify the groups and periods of the elements 2. The term “periodic” is based on the discovery that elements show patterns in their chemical properties at certain regular intervals. Lesson 2 Reactive and nonreactive metals After going through this module, you are expected to: 1. Visualize trends, 3D orbitals, isotopes, and mix compounds. Ideally, this lesson plan is for middle-school science and chemistry teachers, but it could be adapted for other subjects and grade levels. Mendeleev left spaces for elements he expected to be discovered, and today’s periodic table contains 118 elements, starting with hydrogen and ending with oganesson, a chemical element first synthesized in 2002 at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia, by a team of Russian and American scientists. Interactive periodic table showing names, electrons, and oxidation states. Choose between a Google Slides version or printable PDF that can be used as an assessment tool a. These easy-to-read Periodic Tables are current with a full 7th period and groups labels 1-18. Its story is over 200 years old, and throughout its history, it has been a subject for debate, dispute and alteration.Īttempts to classify elements and group them in ways that explained their behavior date back to the 1700s, but the first actual periodic table is generally credited to Dmitri Ivanovich Mendeleev, a Russian chemist who in 1869 arranged 63 known elements according to their increasing atomic weight. This no-prep Periodic Table chemistry activity, in print and digital, engages students with labeling the categories of the periodic table. Go into any scientist’s office or lecture hall anywhere in the world and you are likely to see one. There is no more enduring reflection of science than the Periodic Table of Chemical Elements, which sheds light not only on the essence of chemistry but physics and biology as well. ![]()
