B.  β + decay Q . 2 3 8 9 2 U → 2 3 4 9 0 Th + .......... C.  Fission R . 1 8 5 8 3 Bi → 1 8 4 8 2 Pb + .......... D.
Options
- Aa-q;b-p;c-s;d-r;
- Ba-q;b-s;c-p;d-r;
- Ca-q;b-r;c-s;d-p;
- Da-q;b-r;c-s;d-p;
Correct answer
A. a-q;b-p;c-s;d-r;
Step-by-step solution
(p) ln α decay, the mass number decreases by 4 and atomic number decreases by 2 . (q) ln β + decay, mass number remains unchanged while atomic number decreases by 1 . (r) ln fission, parent nucleus breaks into almost two equal fragments. (s) ln proton emission, both mass number and atomic number decreases by 1 .
