Hydrogen Breakthrough Could Open The Road To Carbon-free Cars
A new breakthrough in hydrogen storage technology could remove a key barrier to widespread uptake of non-polluting cars that produce no carbon dioxide emissions. UK scientists have developed a compound of the element lithium which may make it practical to ...
Atomic weights of five elements tweaked
lithium, boron, carbon, nitrogen, oxygen, silicon, sulfur, chlorine and thallium. Elements such as fluorine, aluminum, sodium and gold have just one stable isotope and thus do not exhibit variations in their atomic weights. The new intervals may cause some ...
Atomic Weights Tweaked for 5 Elements
In 2010, the IUPAC replaced standard atomic weights with intervals for hydrogen, lithium, boron, carbon, nitrogen, oxygen, silicon, sulfur, chlorine and thallium. Elements like fluorine, aluminum, sodium and gold have just one stable isotope and thus do ...
Boron: It's What Makes the Hope Diamond Blue
Boron is carbon's neighbor on the periodic table, which means it can do a passable carbon impression and wriggle its way into the matrix of a diamond. But it has one fewer electron, so it can't quite form the same four perfect bonds. This different ...
The Geometry of Snowflakes -- Oxygen Structure
Why do freezing water molecules arrange ... The four Elements following Hydrogen, Helium(2), Lithium(3), Beryllium(4), and Boron(5), all have box-like shapes. But the next 5, Carbon(6), Oxygen(8), Nitrogen(9), Fluorine(10) and Neon(11) are all spheres.
