Tungsten (W) is mainly in the W+6 oxidation state in most W oxides, with six oxygen atoms surrounding each W atom in an octahedral configuration. In oxidized tungsten (WO3), these octahedra are arranged in a split-angle configuration. In reduced oxides (WOj, 2 < x < 3), complex combinations of WO6 octahedra in split-angle, split-edge, and split-face arrangements are frequently found. The WO4 tetrahedra and WO7 pentagonal dihedra, which are frequently found in fully oxidized and partially reduced compounds, respectively, add to the complexity of the crystal geography of these compounds.

Molybdenum (Mo) is a refractory metal with a melting point of 2620°C. It hosts a small coefficient of expansion, high electrical conductivity, and good thermal conductivity. It does not react with hydrochloric acid, hydrofluoric acid, and alkaline solutions at room temperature, and is only soluble in nitric acid, aqua regia, or concentrated sulfuric acid. Therefore, Mo and its alloys have a wide range of applications and good prospects. In this article, we will describe 6 uses of Mo.

Mo may be a little-known and important element that could be life-threatening when its levels in the body are unbalanced. With 42 protons and 54 neutrons, Mo is located right in the middle of the periodic table, and it is in considerable demand as an alloy for strengthening steel. It's also the only element that keeps most of your food from being lethal.
