| The Elements: A Quiz Deck on the Periodic TableProduct DescriptionMuch more than a simple chart, the periodic table of elements identifies and categorizes chemical elements. But what exactly is an element? What do the numbers on the table signify? And how are the elements arranged? When you dig into these 48 Knowledge Cards, you’ll have many more questions. (But don’t fret: you’ll have the answers, too.) The front of each card delivers a quiz question (e.g., What makes the periodic table “periodic”? or What are the three primary types of atomic bonds?). On the back is a concise, easily digestible response. The Elements covers everything from the ABCs of atomic structure to the KLMNOPQs of electron shells as it leads you on a whiz-bang tour of the periodic table. We carefully shrinkwrapped the contents into a highly charged fusion of facts and fun. Please use caution when opening. Sample Card TextWhat is the purpose of the periodic table of elements? (a) to annoy high school chemistry students (b) to illustrate certain properties of—and relationships among—the various elements (c) to provide an easy way to memorize the chemical symbols (d) all of the above Answer (b) The periodic table lists all the known elements and arranges them in a form allowing the user to ascertain important characteristics of any element by its location on the table. Knowing the physical properties of the individual elements (e.g., mass, color, etc.) is an important part of understanding chemistry. Equally important is knowing the elements’ chemical properties—that is, how they combine to form the roughly 40 million substances (so far) found in nature or artificially produced by humans. Combinations of elements, or compounds, affect every aspect of life and include everything from the air we breathe to the food and water that sustain us. Some elements exist in nature only in compounds. So in addition to providing information about each individual element, the periodic table helps the user answer questions about how different elements will react when combined—questions, for example, like, “Should I have my will prepared before I drop this spoonful of caesium (55) into a glass of water?” | |||||
