1.

The number of `beta`-particles emitted during the change `""_(a)""^(c)Xto""_(d)""^(b)Y` isA. `(a-b)/4`B. `d+[(a-b)/2]+c`C. `d+[(c-b)/2]-a`D. `d+[(a-b)/2]-c`

Answer» Correct Answer - c
For `alpha-Zdarrby2` For `alpha-Adarrby4`
For `alpha-A` and Z doesn t change
`beta-Zuarr` by one unit, A-doesn’t change
`alpha=(c-b)/4,beta=2Xalpha-Zp-Zd, 2X(c-b)/(4)-[a-d]`
=`d+[(c-b)/(2)]-alpha`
