(a) Write the bas

(a) The basic nuclear process involved in the beta decay and emission of β ⁺ in a symbolic form, by a radioactive nucleus is given as:

After β ⁺ particle emission, the mass number (A) remains the same but atomic number (Z) decreases by 1 unit.

(b) In the reactions given :

(i)

Since, a neutrino is emitted, it is a β ⁺ particleemission , thus the other particle emitted is a β ⁺ particle. And thus the atomic number is decreased by 1 and the atomic mass remains same after the nuclear process. So it becomes,

Thus , the value of x is β ⁺ particle i.e. positron, y is 5 and z is 11.

(ii)

_{From the conservation of atomic mass on both the sides of the equation We know that the atomic number of Ne, He is 10 and 2 respectively and the atomic mass of He is 4 . Thus,} a is 10, b is 2 and c is 4.

_{Thus the equation becomes:}
