What is the difference between alpha, beta, and gamma decay?

<p>These are the difference between the alpha, beta and gamma decay:</p><ul><li><strong>Alpha decay:</strong> It reduces mass number by 4 and atomic number by 2. It is the emission of a helium nucleus (2 protons, 2 neutrons).</li><li><strong>Beta decay:</strong> It changes atomic number by ±1 but there is no change in the mass number. It involves a neutron converting into a proton (or vice versa).</li><li><strong>Gamma decay:</strong> Here, there is no change in the atomic or mass number, just the emission of high-energy photons.</li></ul>
