Gamma and neutron charges and masses in radioactive decay

[_Mayday_]

I've just been working on some of the basics of radioactive emissions. I checked my answers in the back of the book and was so supried at what I found. I just want to clear some of these signs. charges and and relative mass.

Gamma $$^1_1\gamma$$

Neutron$$^1_1n$$

I thought that gamma emission had no charge or relative mass. I also thought that the neutron had a relative mass of one, but no charge...

Is the answer book incorrect? Or do I just not trust it enough?

Thanks

As far as I'm aware, you're correct, the book is not.

Could you source that?

Uh... not off the top of my head. Gamma is electromagnetic radiation, and is therefore massless and chargeless. Neutrons are almost equivalent in mass to protons (with negligible difference), and therefore have mass 1, and (as the name suggests) electrically neutral, thus no charge.

You see that is exactly what I thought, but it's not very common for a textbook to be wrong after many students before me would have used it, and it's hard to believe it would not have been spotted. Thank you.

I will consult my teacher
