For elements that lack isotopes with a characteristic isotopic abundance in natural terrestrial samples, the mass number of the nuclide with the longest confirmed half-life is listed between square brackets. These are the students that I will usually let use their color coded periodic table for the duration of the unit and perhaps on quizzes and the test.The latest release of the Periodic Table (dated ) includes the most recent abridged standard atomic weight values released by the IUPAC Commission on Isotopic Abundances and Atomic Weights ( CIAAW), compiled as part of the 2021 Table of Standard Atomic Weights 2021. ![]() If students still struggle with some of this information needed to understand the periodic table, it's usually just a matter of needing to sit down and put it into context with something like ion calculation or bonding. This is enough information to demonstrate a good foundation for moving forward. ![]() I am looking for a couple of family names like noble gases and alkali metals, rows are called periods, columns are families and have the same number of valence electrons. I like to have them do it by memory, not using their webquest or color coded periodic table, and see what they can remember. My goal is to have them reflect upon what they know about the periodic table after they have had a chance to examine it in a variety of ways via webquest, coloring and questions. Also, anyone who has not completed the webquest from the previous day needs to complete that first and both assignments will be check-in for completion first thing tomorrow.Īs most students are wrapping things up with about 10-15 minutes left, I will hand back their K-W-L from the previous day. I have found out that the top of the periodic table works best for easy reference and have provided a student example.Īs a final instruction, I let them know that they need to answer The Family Tie questions that are on the back side of periodic table using their textbook and Color Coding the Periodic Table directions that were provided. They also ask if it matters where they place the key. I find that it is okay for them to use a different color because they have to make a key that can be used as an easy reference. The only question that kids have is if they can use a different color. PRINTABLE PERIODIC TABLE OF ELEMENTS COLOE HOW TOThe directions are fairly straight forward and easy to follow, so students have very little questions about how to accomplish this task. I prefer them to use colored pencils instead markers because they do not bleed through the table. I let them know they should follow the list of instructions and color coordinate each part of the periodic table with the provided colored pencils. The periodic table is blank and only contains the name of the element, symbol, atomic number and mass number. I explain to them that they can use their text book and the Color Coding the Periodic Table portion of the assignment to color the periodic table that is provided. This lesson continues to build on the Crosscutting Concept Patterns by showing students that the arrangement of periodic table reveals patterns in elements' valence electrons, reactivity and other properties.Īfter the video I handout a copy of the periodic table coloring assignment. The activity has students label the major parts of the periodic table in order to distinguish between metals and nonmetals, families and periods, and physical and chemical properties. In this lesson students explore the periodic table using the NGSS Science Practice 2: Developing and using models. The repeating patterns of this table reflect patterns of outer electron states. ![]() This lesson is aligned with the NGSS Disciplinary Core Idea (DCI) PS1.A: The periodic table orders elements horizontally by the number of protons in the atom’s nucleus and places those with similar chemical properties in columns. The goal of the lesson is for students to elaborate on previously learned information show a deeper understanding of the periodic table. This lesson addresses the NGSS HS-PS1-1, "use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms". ![]()
