S-34 is stable. It will not decay.
When bismuth-212 undergoes alpha decay, it becomes thallium-208.
Americium-241 undergoes alpha decay to become Neptunium-237. During alpha decay, an alpha particle (two protons and two neutrons) is emitted, resulting in the conversion of Americium-241 to Neptunium-237.
Polonium-218 undergoes alpha decay to form lead-214, which then undergoes beta decay to form bismuth-214.
Nuclear decay.
There is no equation. Calcium-42 is stable and does not decay. Calcium is also much to light for alpha decay, which requires elements heavier than nickel, so no isotope of calcium undergoes alpha decay.
When bismuth-212 undergoes alpha decay, it becomes thallium-208.
When sulfur-34 ((^{34}\text{S})) undergoes alpha decay, it emits an alpha particle, which consists of 2 protons and 2 neutrons. This process reduces its atomic number by 2 and its mass number by 4, resulting in the formation of phosphorus-30 ((^{30}\text{P})). Thus, the decay can be represented as: [ ^{34}\text{S} \rightarrow ^{30}\text{P} + ^{4}\text{He} ] where (^{4}\text{He}) is the emitted alpha particle.
bismuth 210 decays by beta decay to polonium 210 that decays by alpha decay to lead 206
That depends on the type of decay, alpha and beta decay change the atom into a different element but gamma decay does not.
Americium-241 undergoes alpha decay to become Neptunium-237. During alpha decay, an alpha particle (two protons and two neutrons) is emitted, resulting in the conversion of Americium-241 to Neptunium-237.
If seaborgium undergoes alpha decay, it would create rutherfordium as the resulting element.
Npn decays to Pan-4 and alpha. Only isotopes 234, 235, and 237 of neptunium can undergo alpha decay, the others decay by beta-, beta+, K capture, and/or gamma decay. So the only products of neptunium alpha decay can be protactinium isotopes 230, 231, or 233.
Polonium-218 undergoes alpha decay to form lead-214, which then undergoes beta decay to form bismuth-214.
90Th232 undergoes alpha decay to form 88Ra228. Remember, in alpha decay, a helium nuclei is emitted, comprising two protons and two neutrons. As a result, the atomic number goes down by 2, and the atomic mass number goes down by 4.
Nuclear decay.
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.
Uranium 238 is transformed in thorium 234 by alpha decay.
