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 are entirely forgiven for not knowing this, since they are not especially rare — cerium is about as common as copper. The problem is that they’re difficult to isolate and purify; it wouldn’t be ...

It’s not every day an element gets added to the periodic table. The last time it happened was 2016, when four new elements became official. For these elements, reaching the table was an epic quest ...

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 ...

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 ...

This illustration shows a typewriter with the keys depicted as the periodic table. Hands are typing on it, and the sheet of paper coming out of it shows the words "Tales from the table." Credit: Chris ...

Talent without chemistry often fails. But ... there's no single way to define what makes up the chemistry of a successful team. If everybody's alike and gets along, that might make good "chemistry'' ...

In a significant breakthrough for the scientific community, a new element has been confirmed on the periodic table. This discovery holds potential implications for a wide range of scientific fields, ...

Researchers have directly observed the heaviest atom yet participating in a chemical reaction and forming a molecule. The finding pushes “superheavy” chemistry, which involves extremely massive ...

This year marks the 150th anniversary of the publication of Mendeleev’s Periodic Table of Chemical Elements in 1869. In celebration, the United Nations Educational, Scientific, and Cultural ...
