The periodic table is one of the triumphs of science. Even before certain elements had been discovered, this chart could ...

*Grab samples are discrete samples which are typically, but not exclusively, constrained to mineralization. Grab samples are selective in nature and collected to determine the presence or absence of ...

China mines around 70% and processes around 90% of rare earths. The U.S. is hoping to change that with investment in the ...

Last year, the International Union of Pure and Applied Chemistry (Iupac) revised the atomic weights of gadolinium, lutetium ...

Why do the atomic weights on the periodic table keep changing? Kit Chapman meets the team behind the decimal places ...

Manvendra memorised each element’s name, atomic number, and atomic mass, accurate to two decimal places, and recited them both in sequence and in random order.

The periodic table allows us to understand chemistry at a glance, and you can tell so much about the chemistry of an element just by its position. For example, if you picked up a block of magnesium ...

The periodic table of elements has long been a cornerstone of chemistry, but what if we told you that the elements we know and study today may not be the full picture? Could there really be an ...

The periodic table of elements, or Mendeleev’s table, was created in 1869 by Russian chemist Dmitri Mendeleev. This table organizes all known chemical elements by their atomic number, or the ...

A new version of the periodic table of elements has predicted hundreds of highly charged ions that could be used to create the next generation of optical atomic clocks.

With the addition of four new elements, the seventh row of the periodic table is officially full, the International Union of Pure & Applied Chemistry (IUPAC) announced on Dec. 30.
