How is technetium-99m produced in hospitals? Why does production efficiency vary among pikilonerms and homeotherms? What is the role of agrochemicals in increasing food production? How are borates used in oil and gas production? Why can't pair production take place in a vacuum? What controls...
The periodic table contains 90 naturally occurring elements and several synthetic ones. These naturally occurring elements are generally stable, although some of the heavier elements (such as technetium and promethium) are radioactive.Answer and Explanation: ...
SPECT is a technique similar to PET. But the radioactive substances used in SPECT (Xenon-133, Technetium-99, Iodine-123) have longer decay times than those used in PET, and emit single instead of double gamma rays. SPECT can provide information about blood flow and the distribution of ...
How many neutrons are in the nucleus of technetium-99m? What are the different types of radioisotope dating? How do protons change in alpha radiation? How radioactive is copernicium? How does radioactive dating determine the age of fossils?
CONSTITUTION:The components in non-soluble deposit of fission products to be recovered are mostly noble metals and form an alloy of hexagonal closest packing structure of five elements including moribdenum and technetium. When the fission products noble metals are recovered in lead solving method, ...
and this is where I made a mistake. I had seen that the rarest of all was technetium, so I started betting technetium and winning, and hoarding: I built up a capital of technetium. I hadn't foreseen it was an unstable element that dissolved in radiations: suddenly I had to start all...
Which wehave done before.Elements 95-118 were all produced by us. Elements 1-94 have occurred naturally, though we still have made some synthetically. Technetium, promethium, astatine, neptunium, and plutonium were first discovered because we synthesized them. It wasn’t until later that we ...
MALE STUDENT: Um, Professor Harrison? Then how come in my periodic table here element 43 is “Tc”--that's technetium, right? MALE PROFESSOR: OK, let me add that …Actually, uh, that's the point I’m coming to.Hardly anyone believed that Tacke had discovered a new element.X-ray spe...
LC-MS also shows that complexes formed with the HYNIC conjugate contain fewer coordinating co-ligand molecules than the HYBA conjugate indicating that HYNIC is able to more effectively satisfy the coordination requirement of technetium, perhaps by binding in chelating mode.Robert C. King...
