3. Carbon -14 underwent radioactive decay and emitted beta particles. a. Write an equation to represent this process
?

The decay reaction of Carbon-14 which releases Beta particles, resulting in the element Nitrogen-14

Radioactivity is the process of unstable isotopes to stable isotopes by decay, by emitting certain particles,  

Carbon-14 emits beta β ₋₁e⁰ particles , so the atomic number increases by 1, the mass number remains the same

Reaction

fe 55.85 g/mol and h2o 18.02 g/mol.
