Elements heavier than uranium don’t exist naturally on Earth. Researchers make these massive elements at the end of the periodic table by smashing existing atoms together in particle accelerators.

On the far right side of the periodic table, just beneath oxygen, sits a lesser-known group of elements called the chalcogens ...

This ACS/NSF colloquium was held on Wednesday, November 20 at the National Academy of Sciences in Washington, DC. The event was generously supported by a grant (CHE-1937824) from the National Science ...

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 ...

The periodic table is part of the bedrock of chemistry education. Students use it to look up values like an element’s atomic mass, and it serves as a visual reference for the trends in physical ...

Discovery of four super-heavy chemical elements by scientists in Russia, America and Japan has been verified by experts and formally added to table Four new elements have been added to the periodic ...

The periodic table stares down from the walls of just about every chemistry lab. The credit for its creation generally goes to Dimitri Mendeleev, a Russian chemist who in 1869 wrote out the known ...

How far into the periodic table could you get? Would you be breaking any laws? At what point would your periodic table start ...

The Periodic Table of the Elements is a wonderful aid in understanding chemistry, if you understand the reasons the elements are sorted the way they are. The table itself is a model of information ...
