nothing, but another isotope with the same Atomic Mass is formed
Alpha decay occurs when thorium-231 undergoes radioactive decay to form protactinium-231. In alpha decay, a nucleus emits an alpha particle (two protons and two neutrons) to transform into a nucleus with a lower atomic number.
When an oxygen-19 nucleus undergoes beta decay, a nitrogen-19 nucleus is formed. In beta decay, a neutron is converted into a proton, causing the atomic number to increase by one while keeping the mass number the same.
aluminum-28
When an atom releases both an alpha and a beta particle, it transforms into a different element with a lower atomic number. This process is known as double beta decay. The atom undergoes nuclear transmutation to achieve a more stable configuration.
When 90Sr undergoes beta decay, it forms 90Y (Yttrium-90). In beta decay, a neutron is converted into a proton, and an electron (beta particle) and an antineutrino are emitted.
When magnesium-28 undergoes beta decay, a neutron is converted into a proton, resulting in the formation of an aluminum-28 nucleus. The mass number remains the same at 28, as the total number of protons and neutrons is conserved during beta decay.
Bismuth-214 produces Polonium-214 by beta- decay. It also produces Thallium-210 by alpha decay, though at a much smaller percentage.
Atomic number becomes two units less and atomic mass four units less. Bismuth is the answer.
Beta Particle
When thorium-234 undergoes beta decay, a neutron in the nucleus is converted into a proton, resulting in the formation of protactinium-234, with atomic number 91.
6C14 ---------> 7N14 + -1 e0 Beta particle is emitted and carbon changes into nitrogen
Phosphorus-32 is the radioactive isotope that undergoes beta decay to produce sulfur-32. During beta decay, a neutron in the nucleus of phosphorus-32 is converted into a proton and an electron, resulting in the formation of sulfur-32.
