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.

When an unstable krypton nucleus undergoes beta decay, it transforms into a stable rubidium nucleus. In beta decay, a neutron in the krypton nucleus is converted into a proton, resulting in an increase of one atomic number while the mass number remains unchanged. This process changes the element from krypton (atomic number 36) to rubidium (atomic number 37).
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.
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.
