WebFigure 3. The alpha particle blobs further getting smaller with increasing distance; Approximately at 4 cm, the alpha particles are much smaller (Fig. 4) and if we further … WebAlpha particles don’t travel very fast (compared with beta particles) because they have such a large mass. They carry energy away from a radioactive decay; this energy is of the order of a few MeV and is given to the kinetic energy of the alpha particle; they have a mass of 6.6 x 10 –27 kg so their speed is about 7 x 10 6 m.s -1 – i.e about a fiftieth of the …

During beta decay, the proton in the nucleus is transformed into a neutron and vice versa. If a proton is converted to a neutron, it is known as β + decay. Similarly, if a neutron is converted to a proton, it is known as β – decay. list of meat and cheese trays
