Most nuclear reactions emit energy in the form of gamma rays. The two most common modes of natural radioactivity are alpha decay and beta decay. Protons and neutrons are made up of quarks.
The atomic numbers and mass numbers in a nuclear equation must be balanced. A nuclear reaction is one that changes the structure of the nucleus of an atom. Get 1 1 help now from expert chemistry tutors.

This was the first observation of an induced nuclear reaction that is a reaction in which particles from one decay are used to transform another atomic nucleus. In 1919 ernest rutherford was able to accomplish transmutation of nitrogen into oxygen at the university of manchester using alpha particles directed at nitrogen 14 n α 17 o p. Alpha particles beta particles and gamma rays.
Radioactive substances give off three types of radiation. In nuclear reactions the protons and neutrons are rearranged in the nucleus of the atom to form new elements. In chemical reactions the nuclei of the atoms from the reactants to the products is unchanged.
In nuclear decay reactions or radioactive decay the parent nucleus is converted to a more stable daughter. Nuclear decay reactions occur spontaneously under all conditions and produce more stable daughter nuclei whereas nuclear transmutation reactions are induced and form a product nucleus that is more massive than the starting material. Each radioactive nuclide has a characteristic constant half life t 1 2 the time required for half of the atoms in a sample to decay.
Since first order reactions have already been covered in detail in the kinetics chapter we will now apply those concepts to nuclear decay reactions.
Nuclear decay reactions. Radioactive decay and nuclear particle reactions are two examples of such aggregate processes. The mathematics of poisson processes reduce to the law of exponential decay which describes the statistical behaviour of a large number of nuclei rather than one individual nucleus. Nuclear decay is also called radioactive decay and it occurs in a series of sequential reactions until a stable nucleus is reached. Nuclear reactions release much more energy orders of magnitude more than exothermic chemical reactions.
The two general kinds of nuclear reactions are nuclear decay reactions and nuclear transmutation reactions in a nuclear decay reaction also called radioactive decay 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. 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. Radioactive decay follows first order kinetics.
