Solution

 

(a)

The basic nuclear process involved in the emission of β+ in a symbolic form, by a radioactive nucleus

p β+v

For a beta-plus decay, a proton transforms into a neutron within the nucleus, according to the above reaction.

(b)

(i)

`""_6^11C->_y^zB+x+v`

`=>""_6^11C->_5^11B+_1^0beta+100`

The corresponding y and z are 5 and 11, respectively. The x is the positron

(ii)

`""_6^12C+_6^12C->_a^20 Ne +_b^c He`

`""_6^12C+_6^12C->_10^20Ne+_2^4He`

 The corresponding values of a, b and c are 10, 2 and 4, respectively.
