Technetium-99 has not been found on earth because there are no stable isotopes of Technetium because they are all radioactive. They also have a short half-life and therefore need to be made in a nuclear reactor. It has been detected in some stars, but aside from that the best place to find technetium now is in nuclear reactors.

It has been detected (by its spectrum) in some stars, but aside from that the best place to find technitium now is in nuclear reactors (Tc-99 is a byproduct of uranium fission).

Find one element on the chart that has no stable isotopes?
Technetium, Promethium, and all elements heavier then Bismuth.
Where does technetium come from?
Technetium is now produced in nuclear reactors. Neutrons collide with atoms of uranium or plutonium to form new elements. The technetium is then converted to a compound called ammonium pertechnate (NH 4 TcO 4 ). That compound is then treated with hydrogen gas to obtain pure technetium metal.Technetium has never been found on Earth. It has, however, been found in certain types of stars.
Where could you find neon element?
Neon (Ne) is a natural chemical element; neon is a component of the air but the concentration is only 0,001 818 %.
What does TN stand for in the periodic table. It's on my son's homework assignment and it isn't on the periodic table. Did the teacher make a typo?
I can't find it on the periodic table either, it could be Titanium though. Or it could be as follows, Thallium Terbium Technetium Tellurium Tantalum
How do you find an element's relative?
how do you find an element's group
Did scientists find the element technetium on earth?
Yes, technetium exist on the Earth in uranium ores but only in infinitesimal amounts.
Where would you find technetium?
Technetium is an artificial chemical element and is extracted from fission products, prepared by neutron activation or by irradiation in particles accelerators.
Is technetium a limited resource?
yes technetium is a limited resource. You can only find it in certain parts of the world not that I know of though
Find one element on the chart that has no stable isotopes?
Technetium, Promethium, and all elements heavier then Bismuth.
What is the first man made element on the periodic table?
Chemical Element: technetium(Modern Latin: from Greek, technetos, "artificial"; the first man-made artificial element; radioactive metal)Chemical-Element InformationSymbol: TcAtomic number: 43Year discovered: 1937Discovered by: Emilio Gino Segré (1905-1989), an Italian physicist, and Carlo Perrier of Italy.Element 43 (technetium) was predicted on the basis of the periodic table by Mendeléyev.He suggested that it should be very similar to manganese and gave it the name eka-manganese.Technetium was erroneously reported as having been discovered in 1925, at which time it was named masurium.The element was actually discovered by C. Perrier and Emilio Gino Segrè in Italy in 1937.It was found in a sample of molybdenum bombarded by deuterons.Technetium was the first element to be produced artificially and all its isotopes are radioactive.It is named after the Greek word technetos, meaning "artificial".
How did they find technetium?
Technetium was discovered by Emilio Segre and Carlo Perrier in 1936 at the University of Palermo, Sicily, Italy.They studied a molybdenum foil extracted from the cyclotron out of the Lawrence Berkeley National Laboratory and identified isotopes of technetium.
How could you find out if an element has water inside?
By feeling if said element is "wet" -Dr. Bosch
Where can you find every LEGO element in the world?
Lego land in Denmark
Where can Element skateboards be bought?
One could buy Element brand skateboards from many different places. There are many online retailers available to purchase Element boards from or one could find Element at any local skate shop.

Is silver a suspension?
No, it is a chemical element. You could find it in the periodic table as number 47.
