`Xoverset(beta^(-))toX_(1)overset(alpha)toX_(2)overset(beta_(-))toX_(3)overset(alpha)toX_(4)`
If atomic number and atomic mass number of X are respectively, 72 and 180, then what are the corresponding values for `X_(4)` ?

A radioactive element X disintegrates successively as under If atomic number and atomic mass number of X arc respectively 72 and 180. what are the corresponding values for X_(4)

A redioctive nucleus decays as follows : Xoverset(alpha)(to)X_(1)overset(beta)(to)X_(2)overset(alpha)(to)X_(3)overset(alpha)(to)X_(4) If the atomic number and the mass number of X are 72 and 180 then the mass number and atomic number of X_4 are-

A redioctive nucleus decays as follows : Xoverset(alpha)(to)X_(1)overset(beta)(to)X_(2)overset(alpha)(to)X_(3)overset(alpha)(to)X_(4) If the atomic number and the mass number of X are 72 and 180 then the mass number and atomic number of X_4 are-

(a) What are isotones? (b) A overset(alpha) to A_(1) overset(beta) to A_(2) overset(alpha) to A_(3) The mass number and atomic number of A are 180 and 72 respectively. What are these numbers for A_(3) ?

In a alpha -decay, the sequence is given as X overset(alpha)to X_(1) overset(beta)to X_(2)overset(alpha)to X_(3) . The mass number and atomic number of X are 170 and 62 respectively. Calculate the same values for X_(3) .
