WebCheck it and compare the three points to the example. Keep in mind that this equation shows the left-hand side splitting into the two pieces shown on the right-hand side. Notice how I wrote the alpha particle as the first product in Example #1, but as the second product in Example #2. Some teachers insist on it going second. WebThe second type of radioactive emission is beta particle emission. A beta particle ( β) is a fast moving electron. We use the symbol 0-1e. Note that the isotopic mass for the electron is considered to be zero because it is much, much less than that of a proton or neutron. While it does have mass, it is just too small to worry about.
