How and why alpha decay occurs, its dangers and how to write a balanced nuclear equation for alpha decay.
Question: 1. Write a balanced equation for the: a. alpha decay of lead-210. b. beta decay of chromium-55. c. capture of an electron by bromine-76 2.
A nuclear reaction can be described by an equation, which must be balanced. The symbol for an atom or atomic particle includes the symbol of the element, the mass number, and the atomic number. The mass number, which describes the number of protons and neutrons, is attached at the upper left of the symbol.
Nuclear decay. The emission of. Carbon-14 decays into nitrogen-14 by emitting a beta particle. This is the balanced equation for the reaction: Notice that: the mass number of the nucleus stays.

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. Regardless of the mode of decay, the total number of.
For example, radon decays into polonium when it emits an alpha particle. Here is the equation for that radioactive decay: Beta decay. In beta decay, a neutron changes into a proton plus an.
