When a small piece of sodium is placed in a petri dish with water and phenolphthalein, the sodium becomes a molten ball and darts around the dish, leaving a pink trail. The reactions of potassium, ...

The periodic table arranges all the chemical elements in a specific way. Patterns are visible in the way that elements behave, and this allows us to make predictions about other elements. Gethin: And ...

Still using an old science textbook? It's time to get a new one then, after four new super-heavy elements were added to the periodic table recently. The International Union of Pure and Applied ...

A computer graphic shows how the collision of calcium ions and berkelium atoms produces atoms of Element 117. (Credit: University of California Television) The scientific body in charge of chemistry’s ...

The periodic table stares down from the walls of just about every chemistry lab. The credit for its creation generally goes to Dimitri Mendeleev, a Russian chemist who in 1869 wrote out the known ...

The periodic table has been stamped into the minds of countless generations of schoolchildren. Immediately recognised and universally adopted, it has long since achieved iconic status. So why change ...
