The element was discovered in the fallout of a thermonuclear blast.
New research suggests ordering the elements by atomic radius and ability to attract electrons.
The laws and principles of chemistry seem pretty set in stone. But as a chemist explains, the field is always evolving, including such fundamental principles as what is a chemical bond.
We need phosphorus for life, as well as for fertiliser to help plants grow, but raw supplies are limited.
New research shows how chemical elements mix in the universe. Without this process, you wouldn’t be here.
From heavy metal to lighter than air gas, these elements and others from the Periodic Table are transformed into artworks that go on display from today.
Gold is one of 12 confirmed elements on the periodic table whose discoverer is unknown.
On its own it’s just tin. But mix it with other elements and it turns into a material that helped shape the ancient world.
How do you return Aboriginal remains to their place of origin when you have no record of where they came from? Look to a chemical element that’s laid down in teeth as people grow up.
2019 is the International Year of the Periodic Table. The person who typically gets credit for its creation is Dimitri Mendeleev. But there were many more chemists who should be recognized.
Wishing you a Happy International Year of the Periodic Table of Chemical Elements on the occasion of its 150th birthday in 2019!
Exactly 150 years after Mendeleev’s classic formulation, it’s time for one for the resource-hungry 21st century.
There have been some rather wacky looking suggestions for arranging the chemical elements.
Alongside their famous dangers, radioactive materials have many beneficial uses. With as many more predicted as have already been discovered, nuclear physicists are searching for more isotopes.
Rare earth elements aren’t actually that rare - but they certainly are useful. Erbium is used right now in the internet’s optical fibre network, and could one day be applied in quantum networks.
Until the recent observation of merging neutron stars, how the heaviest elements come to be was a mystery. But their fingerprints are all over this cosmic collision.
Boron is the hidden ingredient in a lot of our technology. Get to know this plucky little element.
The periodic table is one of the classic images of science that is found in labs as well as on t-shirts, mugs, even set to music. But what exactly is the periodic table?
From the discovery of gravitational waves, to the Pokémon Go phenomenon to the Census debacle, it’s been a big year in science and technology.
