Question #b30c9
1 Answer
The resulting isotope is chlorine-35.
Explanation:
Your goal here is to complete the nuclear equation given to you by using the fact that the radioactive nuclide undergoes a beta minus decay.
As you know, when a beta minus decay, more commonly called beta decay, a neutron located inside the nucleus of a radioactive nuclide is being converted to a proton.
At the same time, an electron, also called beta particle, and an electron antineutrino are being emitted from the nucleus.
)
In your case, you have
3516S→AZ?+−0−1e+¯νe
Now, in a nuclear reaction, mass and charge are conserved. This means that you will have
35=A+0→ conservation of mass
16=Z+(−1)→ conservation of charge
You can thus say that
A=35 andZ=17
Grab a Peridoc Table and look for the element that has an atomic number, i.e.
The resulting isotope is chlorine-35, which means that the balanced nuclear equation that describes the beta minus decay of sulfur-35 looks like this
3516S→3517Cl+−0−1e+¯νe
