Question

(a) Write symbolically the process expressing the `beta^(+)` decay of `._11Na^(22)`. Also write the basic nuclear process underlying this decay.
(b) Is the nucleus formed in the decay of the nucleus `._11Na^(22)`, an isotope or isobar?

Answer 1

(a) `underset (underset(("parent nucleus"))darr )(._11Na^(22)) tounderset (underset(("Daughter nucleus"))darr )(._10Ne^(22))+underset (underset((beta^(+)))darr )(._(+1)e^0)+underset (underset("Energy")darr )(Q)`
The basic nuclear process is decay by emission of `beta^(+)` particle.
(b) The nucleus formed in the decay of `._11Na^(22)` is obviously an isobar having same mass number but different charge number.
