If `._(92)U^(238)` changes to `._(85)At^(210)` by a series of `alpha`-and `beta` -decays, the number of `alpha` and `beta`-decays undergone is .

If ""_(92)U^(238) changes to ""_(85)At^(210) by a series of alpha and beta decays, find the number of alpha and beta decays undergone

._(92)U^(238) changes to ._(85)At^(210) by a series of alpha -and beta -decays. Find the number of alpha -decays undergone ("an integer") .

Change of atomic number and mass number for alpha & beta decay.

Fill up the blank spaces: 92U238 decyas to 85X212 by emitting alpha and beta particles serially. Then the number of alpha and beta particles emitted are ________ and __________.

What are alpha , beta and gamma decays?

If ._92 U^238 undergoes successively 8 alpha- decays and 6 beta- decays, then resulting nucleus is.

If ._92 U^238 undergoes successively 8 alpha- decays and 6 beta- decays, then resulting nucleus is.
