Product Description

The Periodic Round Table PRT-150 3-Dimensional Periodic Table offers a new perspective on the conventional periodic table, making it a excellent gift for chemists, students, or friends with a love of science. The Periodic Round Table can also be used as an educational tool in a classroom or laboratory setting. Made of eight circles made of solid hardwood that stack into a round pyramid, each circle has a guide pin to keep the stack upright and a marker on the side to align each element with its neighbors as in a standard periodic table. Elements are indicated by their chemical symbol and associated atomic number – the number of electrons carried by a single atom of the element. Each level in the Periodic Round Table contains two or more elements classified by scientists into groups called “blocks”.

Periodic Round Table Breakdown by Level

• Top Level: Block 1S - Hydrogen (H) through Helium (He)
• 2nd Level: Block 2S - Lithium (Li) through Beryllium (Be)
• 3rd Level: Blocks 2P, 3S - Boron (B) through Magnesium (Mg)
• 4th Level: Blocks 3P, 4S - Aluminum (Al) through Calcium (Ca)
• 5th Level: Blocks 3D, 4P, 5S - Scandium (Sc) through Strontium (Sr)
• 6th Level: Blocks 4D, 5P, 6S - Yttrium (Y) through Barium (Ba)
• 7th Level: Blocks 4F, 5D, 6P, 7S - Lanthanum (La) through Radium (Ra) including Lanthanoids
• 8th Level: Blocks 5F, 6D, 7P, 8S - Actinium (Ac) through Meitnerium (Mt) including Actinoids and additional blank spaces up to atomic number 120 for future discoveries

While the first attempts at creating a table of the chemical elements can be traced back to the 18th century, the standard periodic table form commonly encountered today was devised by Horace Deming in the early 20th century. The Periodic Round Table builds upon the mathematical regularity of the standard periodic table by using cylindrical symmetry to display the underlying quantum orbitals of the elements. The circular map provides more information about the ordering of the elements than a flat periodic table chart, because it aligns with the order in which electron shells are filled, making it useful for explaining nuances of quantum physics.

The Periodic Round Table is produced in hardwood in Northfield, Vermont, U.S.A.

Periodic Round Table PRT-150 3-Dimensional Periodic Table Review

I appreciate well-made products, and this one does not disappoint. The discs are real hardwood and the lettering indeed looks as permanent as the wood itself. It will stand up to the rigors of my toddler playing with it, and when he's done it still looks great (and is thought-provoking) when I stack it on my desk. The form is actually playful in its simplicity, it is very much like a child's stack toy.

As hard as it is to imagine the discovery of new elements, with this product it is pretty easy to see how they might fit into the overall table and relate to the other elements. The ordering of the elements and visual appearance of the product bring back mental images of orbital probability fields from high-school chemistry class whenever I look at it, it definitely has affected what I think about when I see the periodic table. Obviously I don't make my living thinking about chemistry, but I do appreciate having this to ponder upon.
