(a)
Interpretation:
An equation for the neutron capture reaction and for the reaction in which the product of this reaction decays by beta-emission has to be written.
Concept introduction:
Balancing
- The sum of the mass numbers of the reactants should be equal to the sum of mass numbers of the products in the reaction.
- The sum of
atomic numbers (or the atomic charge) of the reactants should be equal to the sum of atomic numbers (or the atomic charge) of the products in the reaction.
(b)
Interpretation:
Half-life of Sodium-23 has to be determined.
Concept introduction:
Concept Introduction:
