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 ...

A pure substance made from more than one type of element chemically bonded together. Elements bond in fixed ratios and so can be represented by a chemical formula. For example, sodium chloride has the ...

Helium, a noble gas, was long believed to be 'too aloof' to react with the other elements on the periodic table. Now, however, scientists have provided a theoretical explanation of how helium may be ...

Chemists and material scientists have often focused on the properties of previously reported compounds, but neglect numerous unreported but chemically plausible compounds that could have interesting ...

Noble gases—helium, neon, argon, krypton, xenon, and radon—have long been believed to be the least reactive elements on the periodic table. Helium’s composition in particular, with its full outer ...

Matthew Addicoat receives funding from EPSRC and the Royal Society. The universe is flooded with billions of chemicals, each a tiny pinprick of potential. And we’ve only identified 1% of them.

The discovery opens a path to the sustainable synthesis of anti-inflammatory and anti-tumor agents. Scientists at UBC Okanagan have revealed how plants create mitraphylline, a rare natural substance ...
