3. Molybdenum
   Molybdenum is a lustrous silvery coloured metal. In many instances, it shows a resemblance to tungsten with which it tends to be paired in the transition series in the periodic table, but their chemistries tend to show more distinct differences than might be expected. Molybdenum has a high melting point and applications for the pure metal take adva…

8. Molybdenum
   `Molybdenum` (from the Greek meaning `lead-like`), is a Group 6 chemical element with the symbol `Mo` and atomic number 42. It has the sixth-highest melting point of any element, and for this reason it is often used in high-strength steel alloys. Molybdenum is found in trace amounts in plants and animals, although excess molybdenum can be toxic in some animals. Molybdenum was discovered in 1778 by Carl Wilhelm Scheele and first isolated in 1781...
