Naturally occurring tungsten consists of five isotopes whose half lives are so long that they can be considered stable. Theoretically, all five can decay into isotopes of element 72 (hafnium) by alpha emission, but only 180W has been observed to do so with a half life of (1.8 ± 0.2)·1018 yr; on average, this yields about two alpha decays of 180W in one gram of natural tungsten per year. The other naturally occurring isotopes have not been observed to decay, constraining their half-lives to be:
182W, T1/2 > 8.3·1018 years 183W, T1/2 > 29·1018 years 184W, T1/2 > 13·1018 years 186W, T1/2 > 27·1018 yearsTungsten is a non-reactive metal.

Having an electronegativity of 2,36 (after Pauling tables) wolfram (tungsten) is not a metal too reactive; but it is not unreactive.
No, they are very hard and extremely durable though, and they make for a great guys wedding band
Tungsten which as a Industrial Metal for drills and so on may content so harmness or radioactive element, such like Cobalt. But the tungsten ring made for jewelry must not content any harmness element. They should be follow the EU standard safe and hypoallergenic for you.
According to recent research, all five naturally occurring isotopes of tungsten can decay into isotopes of element 72 (hafnium) by alpha emission, but only 180W has been observed to do so with a half-life of (1.8 ± 0.2)×1018 yr; on average, this yields about two alpha decays of 180W in one gram of natural tungsten per year. The other naturally occurring isotopes have been observed to decay, although the half lives are not measured.
The theoretical calculations put their half-lives to be
182W, T1/2 > 8.3×1018 years 183W, T1/2 > 29×1018 years184W, T1/2 > 13×1018 years186W, T1/2 > 27×1018 years
All of the thulium ordinarily found in nature is of a single stable isotope. Like all other elements, thulium has synthetic radioactive isotopes.
Tungsten is a natural chemical element; but tungsten has natural and artificial isotopes.
According to the Wikipedia article, "Tungsten interferes with molybdenum and copper metabolism, and is somewhat toxic to animal life."
Yes, tungsten is used in spaceships. The hardness and density of tungsten as well as its high melting point make it a good material for rocket nozzles.
Tungsten is a metallic element of the periodic table. Because of this, it is not an insulator of energy but a conductor instead.
it is used in the ballasts

Tungsten
Tungsten is the dense metal in fishing sinkers. Lead alloys are common, but lead is toxic.
-Highest melting point of any metal -It's hypo-allergenic -Toxic to life, interferes with copper metabolism in the body
can you dissolve tungsten
Tungsten is not Magnetic :(
That's tungsten. Wikipedia has more in their post on this amazing metal. A link to it is below.
Tungsten is an ideal substitute of the lead fishing sinker. It's strong adhesive, semi-solid state, soft for a long term. Tungsten Heavy Alloys concentrate maximum weight in the smallest possible space. They are more often to be used as counterweight in sporting field, such as fishing sinkers, golf weights, etc. Tungsten weights are an ideal, environmentally friendly alternative to lead weights, which are toxic and increasingly being labeled an environmental hazard. They are harder than steel and extremely dense, tungsten being on average 30 percent smaller than its lead counterpart. Meanwhile, they are smaller than conventional weights, create twice the sound of lead weights and maintain their shape for longer. Tungsten is also used in the production of other fishing applications, such as tungsten-carbide line cutters and tungsten powder coating for fishing lines.
There are none, tungsten is a pure element so it is made of only tungsten.
Tungsten is found in wolframite (hence why the Germans called tungsten wolfram).
Tungsten's original name is Wolfram that is why the symbol for Tungsten is a W
No. Tungsten is an element, where as tungsten carbide is an alloy, or a mixture of elements (tungsten, nickel, tantalum, niobium, titanium, and chromium). Tungsten carbide is much easier to work into styles and designs, but does not change the hardness of the metal.
We should be strong as tungsten heavy alloy,tough as tungsten carbide.This is the motto of China Tungsten Online
Tungsten is classified as a metal.
