Silicon is a semiconductor in group IVA of the periodic table with atomic number 14, an atomic weight of 28.086, and a density of 2.33 Mg/m 3. It melts at 1410 C. The electronic configuration of the ...
Why silicon? Well, it is often said that elements close to each other in the periodic table share similar properties and so, seduced by the age-old red herring that "carbon is the element of life", ...
Scientists have developed the first electrically pumped continuous-wave semiconductor laser composed exclusively of elements from the fourth group of the periodic table -- the 'silicon group'. Built ...
Can France claim the first periodic table? Probably not, but a French Geology Professor made a significant advance towards it, even though at the time few people were aware of it. Alexandre Béguyer de ...
