When Dmitri Mendeleev drew up the periodic table, he grouped elements of similar properties. Based on the number of electrons, a scientist can determine which group to place an element into.This pattern is called a period(or row) on the periodic table. How do I read the periodic table? Th...
Elements on The Periodic Table Every chemical element has a specific atomic number, which provides insight into the number of protons present within its nucleus. All isotopes of an element fall under a single cell on the periodic table, since they all share the same atomic number. ...

Periodic table of elements with information on chemical elements like gold, silver, iron, neon, helium, chlorine, copper, cobalt, and more
(IUPAC). Likewise we only list unnamed elements on our table above whose discovery has been tentatively recognized by IUPAC. Thus at this point in time we have not created individual element pages for elements 114 and above as they have not been officially named. Likewise even though some ...
H: This is the symbol for Hydrogen, the most common element in the universe. He: This symbol represents Helium, a noble gas used in balloons and as a cooling medium. Li: This stands for Lithium, a metal used in rechargeable ba...
Drag your finger on the periodic table canvas to update elements automatically or tap on an element to see more details. Tap on an element and all the rest of the related elements are highlighted. Details of a selected element is shown in a beautifully drawn animated element. ...
