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 ...

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 ...

Why it matters: The periodic table organizes elements by atomic number and properties, making it a powerful tool for predicting reactivity and bonding tendencies. Learning made easier: Interactive ...

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 ...

The periodic table of chemical elements hangs in front of chemistry classrooms worldwide and is an icon for science. Yet much was unknown about its history -- until now. The periodic table reflects ...

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.

This wasn’t the first time a jingle has been written about the elements. In fact, a similar song was written in 1959 by Tom Lehrer. But, apart from being fun study tools, this year we have even more ...

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 ...

The Chemistry Graduate Student Association and the American Chemical Society Drexel Student Affiliates had a very important prayer for the afternoon of Oct. 24: A relatively clear day with little to ...
