Question

Write a balanced nuclear equation for the following: The nuclide astatine-218 undergoes alpha emission to give bismuth-214

Answer 1

Answer:

$^{218}_{85}At\rightarrow ^{214}_{83}Bi+^{4}_{2}He$

Explanation:

Hello there!

In this case, since the radioactive reaction for the alpha emission of astatine-218 to bismith-214 involve the release of a helium atom as shown below:

$^{218}_{85}At\rightarrow ^{214}_{83}Bi+^{4}_{2}He$

Whereas the atomic number decreases by 2 and the mass number by 4 in agreement to the release of the Helium atom.
