Step-by-step explanation:

10) From the options provided for this question, gamma particle is the most energetic. Recall that gamma rays are high energy electromagnetic radiation which are capable of causing a high degree of ionization in matter.

11) The bombardment of U-235 with neutrons leads to the reaction;

`U(235)/(92) + n(1)/(0)---> I(138)/(53) + Y(95)/(39) +3n (1)/(0)`

Hence

a = 92, b= 95, c= 53

12) In positron emission, a proton is transformed into a neutron. The mass number of the daughter nucleus is the same as its parent but the atomic number decreases by 1.

Hence;

`Th(231)/(90) -----> e(1)/(0) +Ac (231)/(89)`
