The pure element would like explode on contact with skin. Science Picture Co/Getty Images. All of the elements in the alkali metal group are extremely reactive. If you put pure sodium or potassium metal in water the result will be a fire. The reactivity increases as you move down the periodic table, so cesium reacts explosively.

Earlier versions of the Periodic Table released since 1999. 1 Dec 2018 [current version] including the most recent updates released in June 2018 by the IUPAC Commission on Isotopic Abundances and Atomic Weights () (see related News,released 5 June 2018), and specifically for argon, the assignment of an interval for the new standard atomic weight which reflects the common occurrence of

A compact and easy to use Periodic Table of Elements. Detailed information about the chemical elements, including, atomic number, atomic mass, atomic volume, svg with more classical proportions of element cells, but without information about isotopes.

Students assemble, color, and complete a giant (42.5 x 21.5 inches) 3-D Periodic Table with fold out flaps for each element. The flaps allow this Periodic Table to be filled with information including:- Element Families- Element properties and uses- Elements found in the Human Body- Elements found

It is organized in order of increasing atomic number. There is a recurring pattern called the “periodic law” in their properties, in which elements in the same column (group) have similar properties.

In our large periodic table displays we use larger versions of these tubes: The ones photographed here are about 3" tall, but the other ones look basically identical, just bigger. I chose this sample to represent its element in my Photographic Periodic Table Poster. This year is the International Year of the Periodic Table of Chemical Elements—and today (March 6), the modern version celebrates its 150 th birthday..
