This set of 125 cards is great tool for learning the Periodic Table elements. Color-coded cards let you know to which group the elements belong – yellow – metals; green – metalloids; purple – non-metals; black – recently approved elements (109-118); and red – definition cards. The deck of 125 cards includes 118 element cards, 1 Actinoid card, 1 Lanthanoid card, and 5 definition cards (definitions w/ visual for atomic mass, atomic number, electron arrangement (configuration), and valence. The cards are the size of standard playing cards and include the symbol on the front and symbol, atomic number, atomic mass, name, and electron configuration (arrangement) on the back. An included guide provides handy terms and definitions and a simple explanation for placement within the Periodic Table. This deck of cards would be a handy tool for any chemistry student trying to learn the elements. ~ Donna

Test your Periodic Table trivia with this deck of 48 fact-filled cards. Each laminated card measure 3¼”x 4” and has a question on the front side with the answer and short explanation on the reverse. Questions are multiple choice, true/false, and short answer, and they ask general questions about the elements and the Periodic Table. Use these to review concepts, prepare for tests or just to test your knowledge on the subject. How much do you already know – What are valence electrons? Which element group on the Periodic Table is highly reactive and includes metals or metalloids? How many elements are there? ~ Donna

It's easy to find games to practice, say, multiplication. Chemistry? Well, let's just say your choices are pretty limited. However, Atommate fills in the gap! Versatile, portable, and well-organized, this game features 56 cards and instructions for seven games at several different levels. The deck includes cards for 32 elements, with multiple cards for common elements like oxygen and hydrogen. There are also four Oxidize cards and four Reduce cards which are used in the more advanced games. The element cards feature a lot of information, including the element's atomic number, symbol, name, oxidation states, period, group, valence electrons, electronegativity, melting point, sublimation point, boiling point, atomic mass, phase at room temperature, and electron configuration. While it sounds like a lot, the layout is fairly graphical, so the end result is not too overwhelming. While many of the games involve making compounds, one of them plays like "war," using the atomic numbers, and another challenges players to collect four cards of the same group or period. The most advanced game has players making compounds, with the ability to "steal" other players' compounds using the Oxidation and Reduction cards. Many of the games could be enjoyed by younger players as long as they had some understanding of the chemistry terms and concepts. On a final note, no chemistry is explained in the rules, so you will find the more complex games much more enjoyable if you are currently studying, or have studied, some basic chemistry. On the other hand, I'm sure you can find multiple flashcard and quiz uses for the element cards too! – Jess

If your visual learner needs to learn and remember the elements of the Periodic Table, this is the perfect product. This deck of cards offers photos of the 118 elements based on Theodore Gray's book The Elements along with a lot of information. These aren't your average flash cards! These 4x4 inch cards are glossy finished heavy cardstock and can stand up to hours of viewing. Along with one card for each of the elements, there are other helpful cards in the set. One card offers an explanation of the Periodic Table and suggested activities for the cards like spelling words using the atomic symbol, element scrabble, go fish, or just as flash cards. Another card tells how to read the element cards with explanations of each item on the card. A third card explains the different arrangements of the Periodic Table – standard, wide form, Scerri standard, and Scerri wide form. 2 cards for Actinides and Lanthanides, and another card which lists the elements according to various properties and is used with one of the activities.
On the front of each card you will see a beautiful, clear photo of the element, the atomic symbol, atomic number, name, and atomic weight. On the reverse you will find a large amount of information for that particular element – atomic symbol, number, radius in picometers, name, crystal structure, mini electron shell diagram, placement on the Periodic Table, density, melting and boiling point, electronegativity, number of valences, electron shells, and percent found in the universe, earth's crust, oceans, and humans, when it was discovered, and other basic information. A bar graph at the left of the card shows its placement on the density scale, a bar graph on the right shows the temperature range for solid, liquid, and glass states of the element, and the graph at the bottom shows the electron orbital filling order. Wow, that is a lot of information in one compact place, but everything is placed in such a way that the information is easy to read and isn't super overwhelming.
If you have a student who needs a wonderful visual aid for science, this would be it. They can be used with middle-school age students as well as high school as a helpful reference tool. No one would mind studying the elements when the cards are as interesting and gorgeous as these. - Donna
