Decay by Alpha and Beta Particle Emission

1) An atom of an element with an atomic number of 95 and a mass number of 241 undergoes decay by emission of an alpha particle. What are the atomic number, mass number and name of the product atom?

2) An atom of 63Ni undergoes loss of a beta particle. What are the atomic number, mass number and name of the product atom?

Solution Preview

1)
Because atomic number Z = 95
Mass number A = 241

After an alpha (Z = 2, A = 4) emission,

New element:
Z = 95 - 2 = ...

Solution Summary

This solution walks through the problem in a plain, succinct manner to find the new element names and atomic numbers and masses after the two incidents of alpha- and beta- decay. The solution is just over 100 words in length.
