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 ...

Since the turn of the century, six new chemical elements have been discovered and subsequently added to the periodic table of elements, the very icon of chemistry. These new elements have high ...

Elements are the chemical building blocks of matter. Everything in the universe that takes up space is made of elements. There are 92 elements found in nature and another 20 or so that scientists ...

The periodic table, which arranges all the elements (radioactive or otherwise) according to their structure, contains 118 chemical elements. These are the building blocks of our world.

That pun is based on the fact that the main building blocks in the branch of science are chemical elements, pure substances ...

One such element is Promethium, and a new study from scientists at Oak Ridge National Laboratory has successfully analyzed chemical properties of the rare earth metal some 80 years after its ...

The chemical characteristics of the elements can equally well be studied, for there are the acid- and base-forming elements on the chart, whose zones gradually infiltrate from strong basic to weak ...

Some of the elements of which the numerous compounds have long been very obvious to the human ken are, therefore, from the point of view of their quantity, of very little importance; thus ...

Instead, they may be made of naturally occurring "superheavy elements" beyond those listed in the periodic table — our current best catalog of 118 chemical elements — new research suggests.
