I highly recommend Wonderful Life with the Elements as a companion to the science classroom. Our world, everything we know, can be distilled into 188 elements. The very thought is fascinating in its ...

It is an icon of natural science and hangs in most chemistry classrooms: the periodic table of elements, which is celebrating its 150th birthday this year. The tabular overview is closely linked to ...

Periodic table is an arrangement of all known elements organized on the basis of structure and atomic number. Moving across the periodic table, one finds an increase in the number of protons. Moving ...

Scientists from Massey University in New Zealand, the University of Mainz in Germany, Sorbonne University in France, and the Facility for Rare Isotope Beams (FRIB) discuss the limit of the periodic ...

You'll find it on the wall of nearly every school chemistry laboratory in the land. And generations of children have sung the words, "hydrogen and helium, lithium, beryllium..." in an attempt to ...

All matter–oceans, land, atmosphere, humans, animals, plants, food, materials, products, buildings–is made from 118 known chemical elements. These elements are ordered in the periodic table of ...

The periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called periods) and columns (called groups) according to increasing atomic ...

In their momentary life span, atoms of lawrencium, element 103, may have left a lasting impression on the structure of the periodic table. For the first time, researchers have measured a basic ...
