The quasicrystals were ‘accidentally’ synthesised during the first test of a nuclear bomb in July 1945.
The element was discovered in the fallout of a thermonuclear blast.
For combustion to occur, oxygen must be present. Ammonium nitrate prills provide a much more concentrated supply of oxygen than the air around us.
For too long silver has been used to mark second best but this element deserves more recognition thanks to its antibacterial properties.
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.
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.
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.
