Reactant nuclei and product nuclei

In summary, the conversation discusses the change in mass of 23Na and 24Na in a neutron capture process. While the mass of 23Na decreases, the mass of 24Na increases due to production and decreases from decays. This is represented by a formula that shows a net increase in the number of 24Na atoms over time.

Homework Statement


in the photo, the 23Na form 24Na Am i right?

if i am right, the mass of 23Na should decraese , and mass of 24Na should increase.
but why the solution provided is the mass of 24Na decreses and increases at the time of delta t ?? i can't understand

23Na can capture a neutron to become 24Na.
The number of 23Na atoms decreases, but at a negligible rate.
The number of 24Na atoms increases by the production and decreases from the decays - if you start from 0 and have a constant production rate the net effect is always an increase (but getting slower and slower close to the equilibrium), and this is represented by the formula.
 

Related to Reactant nuclei and product nuclei

1. What are reactant nuclei and product nuclei?

Reactant nuclei are the atomic nuclei that participate in a chemical reaction, while product nuclei are the resulting atomic nuclei after the reaction has occurred.

2. What happens to reactant nuclei during a chemical reaction?

Reactant nuclei undergo changes in their atomic structure and/or composition during a chemical reaction, resulting in the formation of product nuclei.

3. How do reactant nuclei and product nuclei differ?

Reactant nuclei and product nuclei differ in terms of their atomic composition and properties. Reactant nuclei are typically larger and less stable than product nuclei, which are usually smaller and more stable.

4. Are reactant nuclei always consumed during a chemical reaction?

No, reactant nuclei may not always be consumed during a chemical reaction. In some cases, they may only partially react, resulting in the formation of both reactant and product nuclei in the final product.

5. Can reactant nuclei be converted into different product nuclei?

Yes, it is possible for reactant nuclei to be converted into different product nuclei during a chemical reaction, depending on the reactants and conditions involved.
