(a) Write the basic nuclear process involved in the emission of `beta^(+)` in a symbolic form, by a radioactive nucleus. (b) In the reaction given below: `._6C^(11) to ._yB^z=x+v` `._6C^(12)+._6C^(12) to ._aNe^(20)+._bHe^c` Find the values of x,y,z and a,b,c.

(a) The basic nuclear process involved in beta plus decay is transformation of a proton into a neutron within the nucleus according to `._1p^1to._0n^1+e^(+)+v("neutrino")` (b) Applying the principle of conservation of charge number and mass number in the given nuclear reactions, we get (i) `._6C^(11)to._yB^z+x+v` x is an positron, v is neutrino Now, `11=z+0+0 , z=11` `6=y+1+0,y=5` (ii) `._6C^(12)+._6C^(12)to._aNe^(20)+._bHe^c` He is `._2He^4 :. b=2,c=4` Again, `12+12=20+c :. c=4` Also, `6+6=a+b=a+2, :. a=10`
