What evidence would a scientist use to determine the absolute age of a fossil found in a sedimentary rock?
Uranium is the element that decays at a rate that relates to the sample. Uranium is the element that decays at a rate that relates to the sample.
What household item contains the element Francium?
For the most part none do. However, some ceramics contain uranium in their glazes and uranium may form francium as it decays. As a result, some plates may or may not contain an atom of francium at any given time.
What isotope of carbon 12 radioactive?
Carbon 12? The isotope number signifies that there are 12 neutrons AND protons. Carbons atomic number will tell you the number of protons, therefore u subtract the atomic number of Carbon from 12 to find out its neutron count.
How is uranium-238 converted to plutonium-239?
Each isotope of plutonium has its own decay scheme. Plutonium-239 is the most widely used isotope, and it undergoes alpha decay into uranium-235 with a half-life of 2.41 x 104 years (24,100 years). A link is provided to the Wikipedia article on plutonium.
What is the heaviest naturally occurring element?
I have just had to research this question for materials science homework.The answer that i have come up with is -Hydrogen is the lightest stable element with only one proton.Uranium is the heaviest with 92 protons. But scientist have discovered an eliment called eliment 118 that fits just below radon on the periodic table this eliment was supposed to have been discovered in 1999 but was said to have been made up. So i will go with uranium as being the heaviest known stable element for now.
When uranium -238 decays to form thorium-234 the uranium nucleus emitts?
Uranium 238 is aan alpha particles emitter: halflife 4,468.109 years, energy 4,270 MeV.
What is produced when a radioactive element decays?
Energy, various sub-atomic particles, a different element.
What is the definition of the word polonium?
Polonium is a very rare chemical element. It has the atomic number 84. It is produced when uranium decays and is a naturally radioactive metallic element.
How do the properties of radium differ from the properties of the compounds formed by radium?
Radium glows in the dark and is radioactive. When it decays into Radon gas, it emits alpha particles. It is fairly close to its compound radiumchlorite because like radium, it also decays emiting alpha particles. However, radiumchlorite is used to help cure canser. Overal, radium is like its most comon compound but can also have properties not related to its compounds at all.
What element is formed when uranium-238atomic number92ejects an alpha particle?
238U radiates alpha particles and decays via 234Th and 234Pa into 234U, which has a halflife of 245,500 years. (Thorium-234, Protactinium-234, Uranium-234 respectively)
When a mineral spontaneously decays into subatomic particles it has this property?
When a mineral spontaneously decays into subatomic particles, it has this property
What decays into 234Th plus a?
This is the isotope of uranium - U-238.
What is the nuclide produced when uranium 238 decays by alpha emission?
For decays by alpha emission use the general formula: A/Z X --> 4/2 He + A-4/Z-2 Y *Where A is atomic mass and Z is atomic number. So for U-238 238/92 U --> 4/2 He + 234/90 Th
Write a nuclear equation for the indicated decay of Uranium 234?
The equation for the alpha decay of 234U is: 92234U --> 90230Th + 24He representing the alpha particle as a helium nucleus. 234U also decays by spontaneous fission, but the results are somewhat unpredictable, so there is no standard equation.
What evidence would a scientist use to determine the absolute age of a fossil found in a sedimentary rock?
Uranium is the element that decays at a rate that relates to the sample. Uranium is the element that decays at a rate that relates to the sample.
Are trans uranium elements synthetic?
Yes. Plutonium (atomic number: 84) is a trans-uranium element (meaning it has a higher atomic number than uranium (82)). Every element on the periodic table after uranium is man-made.
Uranium 238 decays to lead 206 how much of the oringinal uranium will remain after the third half life passes?
12.5 %
