What do the '238' in uranium-238 and the '14' in carbon-14 mean?
* 238 is the atomic mass of a natural uranium isotope. * 14 is the atomic mass of a carbon isotope.
What is the similarity between uranium-238 and carbon-14 is?
are found in granite
Why is uranium 238 dating better than carbon 14 dating?
Uranium dating is not better but is used for long times in geology; carbon 14 is used for short times in archaeology.
What radioactive element is best suited for determining the age of wooden tools used by prehistoric humans during the last ice age?
Some of the isotopes used for this purpose are uranium-238, uranium-235 and potassium-40. However often the dates are not determined directly from isotopes in the fossils themselves, but instead from isotopes in layers of volcanic rocks above and below the fossils and the age of the fossils are estimated between these two measured dates.
What is one similarity between uranium 238 and carbon 14?
238U and 14C are radioactive isotopes of natural chemical elements.
What is the molar mass of uranium -238?
238 grams/mole The isotopic number is the approximate mass for any element. Such as if I say Carbon 14, the approximate mass is 14 grams/mole. If you are asking what is the mass of one atom of Uranium 238: Then you take the isotopic mass 238 grams/mole and divide by Avogadro's Number 6.022X10^23 atoms/mole this gives you units of grams/atom.
Why do geologists use uranium 235?
They don't. Carbon-14 has a short half-life and is normally only used by archaeologists or anyone working on sediments less than 50,000 years old. It becomes much less accurate after 40,000 years. Scientists used many different isotopes for dating rocks in Radiometric Dating, uranium/lead, potassium/argon and others are used. The half-life in some of these isotopes is measured in millions or billions of years.
What are the examples of isotones?
Isotopes are important due to their uses. Examples include Carbon-14 for dating rocks, Iodine-131 for diagnosing thyroid problems, Cobalt-60 for medical radiotherapy and industrial radiography, and Uranium-235 for producing nuclear energy.
What does uranium 238 become after a series of 14 decays take place?
The final product of the decay chain is the stable isotope 206Pb.
Would Carbon-14 or Uranium-235 be better to date a fossil from the Precambrian time?
uranium-235 dates older objects so uranium-235 would be your answer
What is 17 multiplied by 14?
The Answer is 238. 14 x 17 is 238....
What are the most naturally occurring isotopes?
Carbon-14 and Uranium-235, to name two.
