Question
What is the nuclear symbol for the isotope formed when 167N undergoes beta decay?
Solution
Beta decay is a type of radioactive decay in which a beta particle (an electron or a positron) is emitted. In the case of an electron, the process can be represented as follows:
0/-1 e + ZXA -> ZXA-1
Where:
- 0/-1 e is the beta particle (electron)
- ZXA is the initial atom
- ZXA-1 is the atom after decay
In your case, the initial atom is 167N (where 7 is the atomic number Z, N is the element symbol, and 16 is the mass number A).
So, after beta decay, the atomic number increases by 1 (because an electron is emitted), but the mass number stays the same (because the total number of protons and neutrons is conserved).
Therefore, the nuclear symbol for the isotope formed when 167N undergoes beta decay is 168O.
