Nuclear chemistry, a simple question

I had a simple question concerning nuclear chemistry

In Beta particle capture/decay, is the electron being added to the nucleus or to the electron shell??
Considering that it is called nuclear chemistry leads me to believe that it is incorporated into the nucleus. But this, however, would result in a nucleus with positive and negative charges, one I've never before been taught and have been led to believe that it doesn't exist...
=(

Also, if a neutrino is captured, would the atom be considered to have gained any mass? Or is the mass so small that we disregard it??

Example:
If neutrino capture occurs, which of the following happen?

I.) The mass of the atom remains the same
II.) The charge of the atom remains the same

A.) I
B.) II
C.) I and II
D.) Neither

A proton "captures" an electron, forming a neutron in the nucleus. So charge of the atom stays the same.

C. Neutrino mass is incredibly small. It was thought to be zero for a while.

Thank you!!

So a proton is in effect being turned into a neutron??

 

[loveoforganic]

Yep, coupled with "loss" of an electron.

Do you mean the loss of the electron that was just captured?

Strange how it would be called a loss, if it was just captured~
😱

There's a reason I put it in quotes. It's captured, but technically it no longer exists, at least not as an electron.
