Question

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

____________ → _______ + __________

Answer 1

`^(218)_(85)At\rightarrow ^(214)_(83)Bi+^(4)_(2)He`

Step-by-step 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.
