Do Nuclear Reactions Create New Elements?

Click For Summary
SUMMARY

Nuclear reactions differ fundamentally from chemical reactions by producing new elements through changes in proton and neutron numbers. In a nuclear reaction, the reactants can yield products that have different atomic structures, specifically altering the number of protons, which defines the element. This process results in the formation of new elements, unlike chemical reactions where the elements remain unchanged. The chemical identity of an element is determined solely by its proton count, while variations in neutron numbers affect the atomic mass.

In chemical reactions the individual elements present in the reactants are the same as in the products of the reaction. Is this true for nuclear reaction?

My attempt
Nuclear reactants produce new products, and a new element can be made. This means that a new element with different proton and neutron numbers is formed in a nuclear reaction

More or less correct.

The 'chemical' nature of an element is determined by the number of protons. The atomic (or nuclear) mass can vary with the number of neutrons, but chemically it is still the same element.

Nuclear reactions that change the number of protons will change the element.
