As of 2022, the estimate world reserves of tungsten is 3,800,000 metric tons. Again China contains the greatest reserve at 1,800,000 metric tons of tungsten. The following countries have the next highest reserves: Russia, Vietnam, Spain, and Austria, with an estimated reserve of 400,000, 100,000, 56,000, and 10,000 respectively. [12]
Heavy metals is a controversial and ambiguous term [2] for metallic elements with relatively high densities, atomic weights, or atomic numbers.The criteria used, and whether metalloids are included, vary depending on the author and context and it has been argued that the term "heavy metal" should be avoided.
Europium is a ductile metal with a hardness similar to that of lead. It crystallizes in a body-centered cubic lattice. [11] Some properties of europium are strongly influenced by its half-filled electron shell. Europium has the second lowest melting point and the lowest density of all lanthanides. [11]
Tungsten (also called wolfram) [14] [15] is a chemical element; it has symbol W and atomic number 74. It is a metal found naturally on Earth almost exclusively as compounds with other elements. It was identified as a distinct element in 1781 and first isolated as a metal in 1783.
