Uranium 238 is transformed in thorium 234 by alpha decay.
bismuth 210 decays by beta decay to polonium 210 that decays by alpha decay to lead 206
Isotopes of rutherfordium.
This isotope is transformed in another isotope of another element.

S-34 is stable. It will not decay.
Uranium 238 is transformed in thorium 234 by alpha decay.
The atomic number of an atom undergoing alpha decay decreases by 2. Not asked, but answered for completeness, the atomic mass number decreases by 4.

Nope, Neodymium-144 undergoes Alpha decay to Cerium-140.
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.
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.
That depends on the type of decay, alpha and beta decay change the atom into a different element but gamma decay does not.
It is 90.
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.
