The patented Alexander Arrangement of the Elements presents to the student a learning aid in a natural, logical form of unprecedented clarity. The significant integration of the Rare Earth and Transition elements, usually found in a remote location on standard charts, is the most useful feature for teaching students. And of course students are motivated by the unique & attractive shape! is The construction of the 3D Periodic Table Student Version has been made easy because of the die cut slots and tabs. Instructions are also included so you can hang the constructed 3D Table for as a mobil. Wouldn't you like to see 3D periodic table steps for students and how put together the table? Each chart carries only the atomic number in each of the boxes. Entry of other data and color coding of the groupings is part of the participation activity of the student. Also, an instructor might use several of the Arrangements to illustrate different types of element groupings. Because of the above three main improvements, the 3D Periodic Table Student Version presents to the student a learning aid in a natural, logical form of unprecedented clarity. The resulting 3D Periodic Table form has three parts looping outwards from a central point. The elements in Groups 0, Ia, IIa, IIIb, IVb, Vb, and VIIIb are in the narrowest and tallest part, which forms a tube in the upper part, topped by a `crown' of Hydrogen. From the lower part of this component the sides branch to a more lengthy loop showing groups IIIa, IVa, Va, VIa, VIIa, VIII, Ib, and IIb. From the lower half of this, a third, and longest loop protrudes, the f-block. Periodic Table Student Version (12 sets) - $38.60
