Carbon undergoes beta- decay, with a half-life of years to Nitrogen Beta- decay involves changing a neutron into a proton, so the atomic number goes up by one, while the atomic mass number stays the same. Specifically, a down quark is changed into an up quark, resulting in the change of the neutron into a proton and in the emission of a W- boson, via the weak atomic force, that subsequently decays into an electron and an electron antineutrino.
Uranium is a naturally occurring isotope of Uranium metal. It is the only fissile Uranium isotope being able to sustain nuclear fission. Uranium is the only fissile radioactive isotope which is a primordial nuclide existing in the nature in its present form since before the creation of Earth.

Uranium is separated from Uranium following the diffusion process using Uranium Hexafluoride UF6 gas. Uranium Symbol The symbol or formula for this radioactive isotope is U.
It is also denoted by U Picture 1 — Uranium This fissile material has the following properties: It is a silver colored metal. The molecular weight of this metal is The atomic number for this metal is Its mass number is The critical mass for this radioactive isotope is 52 kg.
Its critical diameter is 17 cm.
Uranium Nucleus There are 92 protons and neutrons in the nucleus of one isotope of this radioactive metal. Uranium Radioactive Decay The unstable nucleus of this radioactive isotope loses energy by emitting ionizing particles for reaching a stable state.
Uranium Decay Equation Following is one decay equation for the Alpha decay of this isotope: Uranium undergoes spontaneous fission during radioactive decay; however, no standard equation can represent this reaction as its results are quite unpredictable.
Uranium Decay Chain The decay chain of this radioactive metal is known as the Actinium Series withThorium being the next isotope in this decay process. It makes Thorium the daughter nuclide of this isotope. Uranium is also known as Actinouranium as it is the parent isotope of the Actinium Series.
It produces Lead as the final stable element of this Alpha decay chain.
Radioactive decay and detection. Carbon goes through radioactive beta decay. 14 6 C → 14 7 N e − ν e. By emitting an electron and an electron antineutrino, one of the neutrons in the carbon atom decays to a proton and the carbon (half-life of ± 40 years) decays into the stable (non-radioactive) isotope nitrogen The emitted beta particles have a maximum energy of Decay mode: Decay energy (MeV). Beta decay is basically the decay of a neutron into the more stable proton The above equation shows the radioactive decay of Carbon by beta emission. Look at the numbers on . A key stage 4 resource for physics GCSE Beta decay The symbols represent isotopes of atoms. There are two numbers before each chemical symbol. Beta decay: Its atomic mass number is 14 so it has 14 particles in total in the nucleus. A natural example of beta emission is the decay of carbon into nitrogen The equation for the decay is.
Here is the complete decay series of this isotope: Uranium Fission Reaction It was the first fissile Uranium isotope to be discovered. When one neutron from U fission reaction causes another nucleus of this metal to undergo fission, it causes the entire chain reaction to continue. It is possible to achieve critical chain reaction with low concentration U In these cases, the neutrons are moderated to lower their speed in the reaction as the chances of fission are greater with slow neutrons than with fast neutrons.
This chain reaction produces many intermediate radioactive mass fragments that are capable of producing energy by undergoing radioactive decay themselves. The fission of Uranium produces high amounts of energy. Most of the total Uranium breaks down into smaller nuclei during fission.
Only a minute amount of this material undergoes neutron capture forming Uranium Uses of Uranium The fact that this isotope is a fissile material able to produce large amounts of heat and energy makes it highly useful in industries.
Uses in Nuclear Reactors It is widely used in nuclear reactors for being able to produce enough electrons to sustain or continue nuclear fission reaction.
However, it needs an electron moderator to help it sustain the chain reaction by slowing down the electrons. This is due to the reason that the concentration of U is very low in naturally occurring Uranium.Here's a video on writing β decay equations.
Science Can you write the nuclear decay equation for the beta decay of iodine? Chemistry Nuclear Chemistry Beta Decay. 1 Answer Ernest Z. Aug 20, Answer: The equation. When finding the age of an organic organism we need to consider the half-life of carbon 14 as well as the rate of decay, which is – For example, say a fossil is found that has 35% carbon 14 compared to the living sample.
Strontium Beta Decay Equation. The Beta decay equation of 90 Sr is given as: 38 90 Sr → 39 90 Y + -1 0 e. Strontium Half Life. The time taken by a decaying radioactive substance to reduce to half of its original amount is referred to as the half life of that substance.
90 Sr has the half life of years or seconds.
It. When beta decay occurs a neutron within the nucleus emits the particle and The above equation shows the radioactive decay of Carbon by beta emission. Look at the numbers on the top line (the nucleon numbers). E.g.
