Interpretation:
Changes are determined in the radioisotope when it undergoes beta emission.
Concept interpretation:
When the ratio of neutrons to protons in the nucleus is much high, then beta emission takes place.
Answer to Problem 1STP
When a radioisotope undergoes beta emission, the
Explanation of Solution
In the beta emission process, the neutron from the nucleus of the isotope breaks apart into a proton that stays in the nucleus, and also a fast-moving electron that is released. This can be represented as follows:
The beta particle that is emitted in this radioactive decay is the beta particle.
Since the beta particle’s electron has no mass (the mass number is zero) and has a -1 charge, we can conclude that when the radioisotope undergoes beta emission, its mass number stays the same, but its atomic number increases.
