Q: Atoms of one element can be transformed into another through which process?


Read this paragraph and choose the correct option from the provided answers:

Not all atoms of an element must have precisely the same mass. Atoms of one element can be transformed into another through nuclear reactions. The compositions of many solid compounds are somewhat variable. Under certain circumstances, some atoms can be divided (split into smaller particles). These modifications illustrate the effectiveness of the scientific method; later experiments and observations were used to refine Dalton’s original theory.

 Choices:

- magnetic reactions

- longer reactions

- developed reactions

- nuclear reactions


A:
nuclear reactions
