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

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
