A radioactive isotope decays in the following sequence : `Aoverset(._0n^1)toA_1overset(alpha)toA_2`
If the mass number and atomic number of `A_2` are 176 and 71 respectively, find the mass number and atomic number of `A_1` and A. Which of the three elements are isotopes?

Verified by Experts

As `alpha=._2He^4`, therefore, mass number of `A_1`
`=176+4=180` and charge number of `A_1=71+2=73`. Similarly, mass number of `A=180+181` and charge no. of `A =73+0=73`. Clearly, elements `A_1` and A are isotopes?
