Color By Element Poster for Review or Assessment of Metal Nonmetal and Metalloid

Use this activity for reviewing or assessing your students understanding of elements on the periodic table. Print it out as a LARGE poster or on a single page. Students have fun while classifying elements based on their grouping as a metal (alkali, alkaline earth, transition, inner transition, and poor metals), nonmetal (halogens and noble gases), and metalloids. They will LOVE it!


Lithium. Lithium (from Greek lithos 'stone') is a chemical element with symbol Li and atomic number 3. It is a soft, silver-white metal belonging to the alkali metal group of chemical elements. Under standard conditions it is the lightest metal and the least dense solid element. Like all alkali metals, lithium is highly reactive and flammable. For this reason, it is typically stored in mineral oil.
