This makes bismuth unique among the heavy metals, and has earned it the status of a 'green element'. For this reason, the world of cosmetic and medicinal chemistry has paid it particular attention.
An element is a substance that cannot be broken down into any other substance. Every element is made up of its own type of atom. This is why the chemical elements are all very different from each ...
Mitch André Garcia considers the disputed discovery of element 104 and takes a look at how the chemistry of this synthetic element is developing. Rutherfordium, the 104th element on the periodic ...
Scientists use the periodic table to quickly refer to information about an element, like atomic mass and chemical symbol ... Since then, the periodic table has evolved to reflect over 150 years of ...

From smartphones to wind turbines, rare earth elements (REEs) are an essential part of the hardware in many advanced technologies. These elements, which include the lanthanides along with scandium and ...
Scientists in Germany have achieved something never seen before: creating a stable boron-carbon triple bond. While triple ...
of~an~element} = \frac{mass~of~an~element~in~the~compound}{relative~formula~mass~M_r} \times 100\) There are six atoms of hydrogen in the compound, so the mass of hydrogen is 6 × 1 = 6.
Players read questions about energy levels and score points by picking the correct element as the answer. Electrons are in regions around the nucleus that are different distances away from the nucleus ...
