Write an equation to represent the beta decay of carbon-14 method

The equation for the beta decay of 14C: From Wikipedia see the Related Link below: By emitting an electron and an anti-neutrino, carbon is changed into stable non-radioactive nitrogen This decay can be used to get a measure of how long ago a piece of once-living material died.

Write an equation to represent the beta decay of carbon-14 method

To know the different kinds of radioactive decay. To balance a nuclear reaction.

Beta Decay - Chemistry | Socratic

The two general kinds of nuclear reactions are nuclear decay reactions and nuclear transmutation reactions. In a nuclear decay reaction A nuclear reaction that occurs when an unstable nucleus emits radiation and is transformed into the nucleus of one or more other elements.

The resulting daughter nuclei have a lower mass and are lower in energy more stable than the parent nucleus that decayed. In contrast, in a nuclear transmutation reaction A nuclear reaction in which a nucleus reacts with a subatomic particle or another nuleus to give a product nucleus that is more massive than the starting material.

Nuclear Decay Reactions

As we shall see, nuclear decay reactions occur spontaneously under all conditions, but nuclear transmutation reactions occur only under very special conditions, such as the collision of a beam of highly energetic particles with a target nucleus or in the interior of stars.

We begin this section by considering the different classes of radioactive nuclei, along with their characteristic nuclear decay reactions and the radiation they emit.

Note the Pattern Nuclear decay reactions occur spontaneously under all conditions, whereas nuclear transmutation reactions are induced. Classes of Radioactive Nuclei The three general classes of radioactive nuclei are characterized by a different decay process or set of processes: The nuclei on the upper left side of the band of stable nuclei in Figure These nuclei decay by a process that converts a neutron to a proton, thereby decreasing the neutron-to-proton ratio.

Nuclei on the lower right side of the band of stable nuclei have a neutron-to-proton ratio that is too low to give a stable nucleus. These nuclei decay by processes that have the net effect of converting a proton to a neutron, thereby increasing the neutron-to-proton ratio.

What is the equation for Carbon decay

This is presumably due to the cumulative effects of electrostatic repulsions between the large number of positively charged protons, which cannot be totally overcome by the strong nuclear force, regardless of the number of neutrons present.

Note the Pattern Nuclear decay reactions always produce daughter nuclei that have a more favorable neutron-to- proton ratio and hence are more stable than the parent nucleus.

Nuclear Decay Reactions Just as we use the number and type of atoms present to balance a chemical equation, we can use the number and type of nucleons present to write a balanced nuclear equation for a nuclear decay reaction.

This procedure also allows us to predict the identity of either the parent or the daughter nucleus if the identity of only one is known.

Key Concepts

Regardless of the mode of decay, the total number of nucleons is conserved in all nuclear reactions. To describe nuclear decay reactions, chemists have extended the X Z A notation for nuclides to include radioactive emissions.

The most notable addition is the positrona particle that has the same mass as an electron but a positive charge rather than a negative charge.Nuclear Decay Reactions.

Just as we use the number and type of atoms present to balance a chemical equation, we can use the number and type of nucleons present to write a balanced nuclear equation for a nuclear decay reaction.

This procedure also allows us to predict the identity of either the parent or the daughter nucleus if the identity of only one is known. A natural example of beta emission is the decay of carbon into nitrogen The equation for the decay is: Notice that the equation balances for both the atomic number and the atomic mass number.

Status: Resolved. 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. . Here is an example of a beta decay equation: Some points to be made about the equation: 1) The nuclide that decays is the one on the left-hand side of the equation.

2) The order of the nuclides on the right-hand side can be in any order. 3) The way it is written above is the usual way.
