Nuclear equations alpha decay

The alpha particles could be obtained from a natural decay process. At present, a variety of particles can be used to bombard nuclei (Table 22-3), some of which are raised to high energies in atom smashing machines. Again, nuclear equations can be written, in which the net charge and the total of the mass numbers on one side must be the same as their counterparts on the other side. [Pg.340]

It can be seen that students can easily balance and complete nuclear equations if they are familiar with the symbols for nuclear particles and know the method of nuclear decay, such as alpha particle emission or electron capture. [Pg.342]

How would you write balanced nuclear equations for the alpha particle decay of radium-226 and the beta particle decay of iodine-131 ... [Pg.343]

The fifth type of radioactive emission, gamma radiation, does not result in a change in the properties of the atoms. As a result, they are usually omitted from nuclear equations. Gamma emissions often accompany other alpha or beta reactions—any decay that has an excess of energy that is released. For example, when a positron collides with an electron, two gamma rays are emitted, a phenomenon usually referred to as annihilation radiation. [Pg.92]

There are three main types of radioactive decay alpha particle emission, beta particle emission, and the emission of gamma radiation. When an unstable isotope undergoes radioactive decay, it produces one or more different isotopes. We represent radioactive decay using a nuclear equation. Two rules for balancing nuclear equations are given below. [Pg.142]

Note also that a new element, radon (Rn), is created as a result of the alpha decay of the unstable radium-226 nucleus. The type of equation shown above is known as a nuclear equation because it shows the atomic number and mass number of the particles involved. It is important to note that both mass number and atomic number are conserved in nuclear equations. The accounting of atomic numbers and mass numbers below shows that they are conserved. [Pg.106]

Exit signs Exit signs are coated with a paint containing phosphors. These phosphors are activated by the radioisotope tritium (jH), produced by bombarding lithium-6 with neutrons to produce lithium-7. The lithium-7 then undergoes alpha decay to produce the tritium.

In nuclear equations, reactant and product nuclei are represented by giving their mass numbers and atomic numbers, as well as their chemical symboL The totals of the mass numbers on both sides of the equation ate equah the totals of the atomic numbers on both sides are also equal There ate four common modes of radioactive decay alpha decay, which reduces the atomic number by 2 and the mass number by 4, beta emission, which increases the atomic number by 1 and leaves the mass number unchanged, positron emission and electron capture, both of which reduce the atomic number by 1 and leave the mass number unchanged. [Pg.908]

RADIOACTIVITY AND NUCLEAR EQUATIONS We begin by learning how to describe nuclear reactions using equations analogous to chemical equations, in which the nuclear charges and masses of reactants and products are in balance. We see that radioactive nuclei most commonly decay by emission of alpha, beta, or gamma radiation. [Pg.908]
