Answer 1

\[_{85}^{217}At \rightarrow _{a}^{b}X +_{2}^{4}He \]
during alpha decay, the compund will release an alpha particle (He, 2 protons and 2 neutrons, giving atomic mass of 2 and atomic mass of 4, identified with the Helium symbol)

it wants the daughter nuclei, which would be X in the equation I wrote. determine the atomic mass and atomic number, as well as the identity of the nucleuts, by balancing the equation

Answer 2

That's what I thought and I have the answer but I have to format it in this program otherwise it says the answer is wrong
