bismuth 210 decays by beta decay to polonium 210 that decays by alpha decay to lead 206
Bismuth-214 produces Polonium-214 by beta- decay. It also produces Thallium-210 by alpha decay, though at a much smaller percentage.
92Au 282Xe +13S
Uranium 238 is transformed in thorium 234 by alpha decay.
Isotopes of rutherfordium.
Atomic number of radium is 88 and that of bismuth is 83. So atomic number is to be reduced by 5. But as alpha is emitted atomic number reduces by 2. So a beta decay is needed which would increase the atomic number by 1. So 3 alpha decay and one beta decay would make radium into bismuth

S-34 is stable. It will not decay.
An alpha particle, 42He
That depends on the type of decay, alpha and beta decay change the atom into a different element but gamma decay does not.

Go nnn and the other one and get it.

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.

Lead-209 undergoes beta- decay to become Bismuth-209 82209Pb --> 83209Bi + -10e + v-e emitting an electron and an electron antineutrino.

Nope, Neodymium-144 undergoes Alpha decay to Cerium-140.
