Consider the nuclear equation below.

which correctly identifies the type of reaction?

a) alpha decay
b) beta plus decay
c) beta minus decay
d) gamma decay

Answer is: B) beta plus decay.

Beta decay is radioactive decay in which a beta ray and a neutrino are emitted from an atomic nucleus.

There are two types of beta decay: beta minus and beta plus.  

In beta plus decay, a proton is converted to a neutron, positron and an electron neutrino, so mass number (A) does not change.

In this nuclear reaction, oxygen (atomic number 8) changes to nitrogen (atomic number 7), because oxygen lost one proton, mass number stays the same (A = 15).

the mass of the cathode increases because ions from the solution get reduced to atoms and become part of the cathode.

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
