The Elements of the Periodic Table There’s Hydrogen, and Helium Then Lithium, Beryllium Boron, Carbon everywhere Nitrogen all through the air With Oxygen so you can breathe And Fluorine for your pretty teeth Neon to light up the signs Sodium for salty times Magnesium, Aluminium, Silicon ...
Note that while hydrogen is normally shown at the top of the Group 1 elements in the periodic table, the term "alkaline metal" refers to the Group 1 elements from lithium downwards and not hydrogen. Hydrogen is the lightest element. It is by far the most abundant element in the universe ...

scores of properties, element names in many languages and most known nuclides (Isotopes). Below the table there is a "Periodic Table Sorted By" section with links that will sort chemical elements by various properties. Each element on the table below links to a detailed page for that element...
As an example, consider the registry number for hydrogen: [1333-74-0]. The calculation is (1*4) + (2*7) + (3*3) + (4*3) + (5*3) + (6*1) = 4 + 14 + 9 + 12 + 15 + 6 = 60. The last digit of the CAS registry numberrmatches the units digit in the number 60,...
What are the heavy metals on the periodic table? What is the element astatine used for? What can you learn about metals from the periodic table? Who discovered transition metals? What is an inert gas on the periodic table? What is hydrogen on the periodic table?
Here, we assessed memory for symbols on the periodic table of elements, which could be presented in symbol format (e.g., H) or word format (e.g., Hydrogen), and compared both to memory for meaningless letters (e.g., J). These stimuli were selected because they all share the same ...
