Haha - I believe this is beta decay? any idea?

frostbite · Answer

I would say so too yea, but should there not be a electro antineutrino too?

frostbite · Answer

electron antineutrino*

anonymous · Answer

Maybe but that's not on our notes or on the test so I'm presuming it's not a part of it. I think it's beta decay!

frostbite · Answer

Well It is beta decay :)

Thank you for your help!

No problem.
and I give you some more than they ask for
The specific kind of beta decay is called beta (-) decay. because it is an electron (e-) that is in the products and not a positron (e+)
