Tungsten (synonym wolfram) [7440-33-7], chemical symbol W, atomic number 74, and relative atomic mass (i.e., atomic weight) 183.84(1), is the heaviest metal of group VIB (6) of Mendeleev’s periodic chart. Its chemical symbol, W, is from the German wolfram, from the mineral wolfram...
These properties account for tungsten's primary application, the manufacture of alloys. An alloy is made by melting and mixing two or more metals. The mixture has properties different from those of the individual metals. SYMBOL W ATOMIC NUMBER 74 ATOMIC MASS 183.85 FAMILY Group 6 (...

Potassium was identified during the Middle Ages, and its element abbreviation is "K" for kalium, a medieval Latin term for potash. W stands for tungsten because it was first identified in 1780 within the mineral known as wolframite, by French scientistAntoine Lavoisier(1743–1794). Finally, sod...

There are 118 elements in the periodic table and each element has its unique symbol which usually consists of one or two alphabets. Usually, the first alphabet is uppercase and the second alphabet is in lowercase.Answer and Explanation:
This is one reason IC developers have been looking for conducting materials for use in IC fabrication having lower electrical resistance. Present IC technology typically makes use of tungsten (chemical symbol W) and aluminum (A1) as conductors. Both have adequate electrical conductivities in present ...
