Write a nuclear equation for positron emission by each nuclide.

(a) C-11

(b) N-13

(c) O-15

Solution 63P:

Here, we are going to write a nuclear equation for positron emission by each nuclide.

Positron particle is defined as

Proton → Neutron + emitted positron

The nuclear equation is

11p 01n + +10e

Thus, When an atom emits a positron, its atomic number decreases by 1 because it has one

less proton after emission.

(a) C-11
