The atomic number and mass number of daughter product is 206 and 82

Explanation:

The atomic weight of uranium is 292 dalton and the atomic number is 92.

When this radioactive atom emits 8 alpha particles then its atomic weight is decreased by 8*4=32units and the atomic number is decreased by 8*2=16 unit. As a result the newly formed daughter atom have an atomic weight of 206 dalton and atomic number of 76 units.

Now the newly formed daughter atom emits 6 beta particle then its atomic weight will remain unchanged but the atomic number will be increased by 6 units. As a result final atom will have an atomic weight of 206 dalton and atomic number 82.
