There have been some rather wacky looking suggestions for arranging the chemical elements.
A particle physicist explains just what this keystone theory includes. After 50 years, it's the best we've got to answer what everything in the universe is made of and how it all holds together.
People long assumed all the elements we see now were created during the Big Bang. But on May 2, 1952, an astronomer reported spotting new elements coming from an old star and changed our origin story.
Fill a tank with water, sugar, and old mobile phones. Add bacteria and stir. Result? Rare earth metals. This is biomining, and it's the way of the future.
The world is made of tiny building blocks called 'elements'. Scientists have worked out how fast some elements change into other elements. That gives us a very big clue about how old the Earth is.
Dust can be instructive. The analysis of those collected around the comet 67P/Churyumov-Gerasimenko provided new information on the history of the solar system.
The precious metal is literally extra-terrestrial, produced in the heart of the stars. How and under what conditions? Scientists know more thanks to a double astrophysical observation.
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?
As four new chemical elements are named, here's all you need to know.
Some 18 elements have had placeholder names derived from the Latin to stop scientists fighting over what their discoveries should be called.
New elements found in the reactions of nuclear tests during World War II sparked the hunt for additions to the periodic table.
They might only last for a fraction of a second but four new elements have finally won their place in the periodic table. The hunt is now on to find even more.
