write down the balance chemical equation for the following reaction 4Be, 17cl ,2He,13Al
Answers
Answer:
equations
Changes of nuclei that result in changes in their atomic numbers, mass numbers, or energy states are nuclear reactions. To describe a nuclear reaction, we use an equation that identifies the nuclides involved in the reaction, their mass numbers and atomic numbers, and the other particles involved in the reaction.
Types of Particles in Nuclear Reactions
Many entities can be involved in nuclear reactions. The most common are protons, neutrons, alpha particles, beta particles, positrons, and gamma rays, as shown in Table 1. Protons

and neutrons

are the constituents of atomic nuclei, and have been described previously. Alpha particles

are high-energy electrons, and gamma rays are photons of very high-energy electromagnetic radiation. Positrons

are positively charged electrons (“anti-electrons”). The subscripts and superscripts are necessary for balancing nuclear equations, but are usually optional in other circumstances. For example, an alpha particle is a helium nucleus (He) with a charge of +2 and a mass number of 4, so it is symbolized

He
. This works because, in general, the ion charge is not important in the balancing of nuclear equations.
Although many species are encountered in nuclear reactions, Table 1 summarizes the names, symbols, representations, and descriptions of the most common of these.
