What does U 235 decay into?
Here is the complete decay series of this isotope: Uranium-235 →Thorium-231 → Protactinium-231 →Actinium-227 →Thorium-227 →Radium-223 →Radon-219 →Polonium-215 →Lead-211 →Bismuth-211 →Thallium-207→ Lead-207 (stable).
How far back can carbon 14 date?
C (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to approximately 50,000 years ago, although special preparation methods occasionally permit accurate analysis of older samples.
Is u238 radioactive?
While 238U is minimally radioactive, its decay products, thorium-234 and protactinium-234, are beta particle emitters with half-lives of about 20 days and one minute respectively.
What is the daughter product of carbon 14?
nitrogen-14By emitting an electron and an electron antineutrino, one of the neutrons in the carbon-14 atom decays to a proton and the carbon-14 (half-life of 5,700 ± 40 years) decays into the stable (non-radioactive) isotope nitrogen-14.
What is the daughter nucleus of this decay?
Thus, negative beta decay results in a daughter nucleus, the proton number (atomic number) of which is one more than its parent but the mass number (total number of neutrons and protons) of which is the same. For example, hydrogen-3 (atomic number 1, mass number 3) decays to helium-3 (atomic number 2, mass number 3).
Why is U 238 more stable than u235?
The instability of uranium comes primarily from the electric repulsion of the protons from each other. … But U-238 has 3 more neutrons than does U-235. The neutrons provide the nuclear force that holds the nucleus together. So the repulsive forces are the same, but the glue is stronger for U-238.

What is difference between uranium and plutonium?
The primary difference is the atomic number: uranium has 92 protons, plutonium has 94 protons. … Plutonium-239 is easier to fission than uranium-235, produces more neutrons per fission, and has a smaller delayed neutron fraction. So plutonium-239 makes a better reactor fuel and nuclear weapon.
Which has higher binding energy parent or daughter nucleus?
20. Four nuclei of an element undergo fusion to form a heavier nucleus, with the release of energy. Which of the two — the parent or the daughter nucleus — would have higher binding energy per nucleon? Daughter nuclei are more stable than parent nuclei.
What is the final daughter of uranium?
thorium 234A nucleus of uranium 238 decays by alpha emission to form a daughter nucleus, thorium 234.
What are the daughters of uranium?
Derived from the chemical sciences, the term “daughters of uranium” describes the radioactive decay chain of naturally occurring uranium (U-235 being the crucial element for sustaining a nuclear chain reaction) while evoking generations born into an uncertain future.
What is a daughter nucleus?
The original nucleus is called the parent nucleus, and the nucleus remaining after the decay is called the daughter nucleus. … If a nucleus emits an alpha particle, it loses two protons and two neutrons; therefore, the daughter nucleus has an atomic mass of 4 less and an atomic number of 2 less than the parent nucleus.
How is C 14 formed?
Carbon-14 is continually formed in nature by the interaction of neutrons with nitrogen-14 in the Earth’s atmosphere; the neutrons required for this reaction are produced by cosmic rays interacting with the atmosphere.
How is carbon 14 used in medicine?
Carbon-14, which is radioactive, is the isotope used in radiocarbon dating and radiolabeling. … medically important radioactive isotope is carbon-14, which is used in a breath test to detect the ulcer-causing bacteria Heliobacter pylori.
Why is U 235 better than u 238?
U- 235 is a fissile isotope, meaning that it can split into smaller molecules when a lower-energy neutron is fired at it. … U- 238 is a fissionable isotope, meaning that it can undergo nuclear fission, but the neutrons fired at it would need much more energy in order for fission to take place.
