An international team of scientists has shed light on the extreme ends of neutron and proton numbers. Their goal is to investigate the limits of the periodic table of chemical elements. How far can ...

One hundred fifty years after Russian chemist Dmitri Mendeleev published his system for neatly arranging the elements, the periodic table it gave birth to hangs in every chemistry classroom in the ...

Recognize these rows and columns? You may remember a detail or two about this mighty table’s organization from a long-ago chemistry class. Elements are ordered according to their number of protons, or ...

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 ...

You know the periodic table that hung on the wall of every science class you took at school? As of today, it’s wrong. Or more precisely, it's inaccurate. One of the biggest changes in decades is set ...

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 ...

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 ...

Tech blog The Beacon recently posted an interesting twist on the periodic table. If you weren't asleep in high school chemistry, you'll recall the periodic table as a colorful chart that your teacher ...
