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 ...

These rules help in identifying and writing chemical symbols consistently across all elements. The symbol serves as a shorthand notation for each element's name in formulas and equations, making ...

It happens all over the periodic table. The chemical symbol for lead is Pb. For mercury, Hg. For antimony, Sb. My chemistry teacher in high school cracked up every time she referred to the symbol for ...

The International Union of Pure and Applied Chemistry Joint Working Party has announced the official names and symbols of the chemical elements formerly known as 113, 115, 117 and 118. The proposed ...

For the last fifty or so years, the periodic table has been incomplete. Elements after uranium on the periodic table have been synthesized for the past few decades, but there were always a few missing ...

This year is the International Year of the Periodic Table of Chemical Elements—and today (March 6), the modern version celebrates its 150 th birthday. To find out more about the table and how new ...

Four new elements now have names. In December, the International Union of Pure and Applied Chemistry officially recognized the discovery of elements 113, 115, 117 and 118, filling out the seventh row ...

In Cambridge, Massachusetts, right near the MIT campus, there’s a great little bar called “Miracle of Science.” It’s as if someone took everything from my science-outreach-filled dreams and made it a ...

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 ...
