Question

What happens to an isotope when it emits a beta particle relative to its atomic number and atomic mass number?

Answer 1

well the beta particle is like an electron, for a nucleus to emit a beta particle , a neutron must turn into an electron, and by conservation of mass and charge, the particle left in the nucleus is a proton,

so what is the net change?

Answer 2

remember that atomic number is the number of protons in the nucleus,
and atomic mass is the total number of nucleons (protons+neutrons )

Answer 3

any questions?

Answer 4

no that is all. thank you for your help! :)

Answer 5

So what is the net change in atomic number?
and what is the net change in atomic mass?

Answer 6

oh i dont know.... thats all the question says.
