What is the daughter nucleus (nuclide) produced when 210po undergoes alpha decay?

Alpha decay is defined as emission of alpha particle which is from the parent nuclei to form daughter nuclei.

Here, parent nuclei is with atomic mass 210 and atomic number 84. Similarly for  alpha particle, atomic mass is 4 and atomic number is 2. After emission of alpha particle, atomic number of Po-210 get reduced by 2 and atomic mass gets reduced by 4. The resultant  atomic number and atomic mass will be 82 and 2016 respectively. This represent the isotope of lead, .

The reaction will be as follows:

Therefore, the daughter nuclei will be .
