Question

a carbon nucleus emits a particles and changes into nitrogen according to the equation

Answer 1

Carbon-14 emits Electron and changes into Nitrogen using the lower Equation,
                              ¹⁴₆C  →   ¹⁴₇N  +   e−

Answer 2

Hello Dear.

Here is the answer---

→→→→→→→→→

A Carbon Nucleus emits a beta particles and changes into the Nitrogen.

The Reaction for the above is---

               ₆C¹⁴  -------------     ₇N¹⁴ +  ₋₁e⁰

A Radioactive Carbon Nucleus ₆C¹⁴, having 14 nucleons (6 protons and 8 neutrons) emits a  β  particles and changes to a new nucleus nitrogen ₇N¹⁴ having 14 nucleons (7 Protons and 7 Neutrons).

This change is represented above in the form of the equation.

Hope it helps.


Have a nice day.
