On the far right side of the periodic table, just beneath oxygen, sits a lesser-known group of elements called the chalcogens ...
If it’s been a while since you’ve taken a chemistry class, you’re lucky – over time, the periodic table has been expanding as ...
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.
There are lots of different substances but only just over a hundred elements. An element is a substance that is made up of only one kind of atom. The atoms in a particular element are the same as each ...
The periodic table is everywhere. Our classrooms. Our offices. Our labs. Its design has even inspired copycat versions categorizing desserts, superheroes, and more. People across the world, scientists ...
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 isn’t just a list of elements—it’s a map of predictable patterns called periodic trends. These trends, like atomic radius, electronegativity, and ionization energy, help scientists ...
The United Nations have proclaimed 2019 to be the International Year of the Periodic Table of Chemical Elements (IYPT 2019) to mark the 150th anniversary of the classification system that decorates ...
Kosuke Morita led the Japanese team at the Riken Institute Four chemical elements have been formally added to the periodic table, completing the scheme's seventh row. They are the first to be included ...
Mendeleev’s chemical grid system defined our world – and the rarer elements it classifies are vital to modern life This year marks the 150th anniversary of the publication of the first periodic table.
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 ...
