In beta decay, a neutron in the nucleus of an atom is converted into a proton and an electron (the beta particle) is emitted. The atom's atomic number increases by 1, while its mass number remains the same.
Let's assume we are starting with sodium (Na), which has atomic number 11 and mass number 24:
The equation for beta decay can be summarized as follows:
\[ \text{A} \rightarrow \text{B} + \beta^- + \overline{\nu} \]
Where:
- A is the original nuclide (sodium)
- B is the resulting nuclide after beta decay.
We can hypothesize that Na undergoes beta decay:
- A: \( ^{24}_{11}\text{Na} \)
- B: After beta decay, sodium (Na) converts to magnesium (Mg), which has atomic number 12.
- C: The remaining values after decay.
Based on these details, we can now fill in the missing parts (A, B, C):
- A: \( ^{24}_{11}\text{Na} \) (24 is the mass number and 11 is the atomic number, matches with g. 25, as it will be converted to 12.)
- B: \( ^{24}_{12}\text{Mg} \) (Matches with c. Mg.)
- C: The atomic mass after decay will stay the same, so it is still 24. (Matches with a. 24.)
By making logical deductions:
- A: (This would correspond to g. 25 if considering the mass number)
- B: c. Mg
- C: a. 24
So the final matches would be:
- A: g. 25
- B: c. Mg
- C: a. 24
Please note that I may have stated sodium, but if you mean a different element (like odium), please clarify so that I can adjust the specifics accordingly!
