Respuesta :
The model of atoms undergoing nuclear fission will decrease in size while that of atoms undergoing nuclear fusion will increase in size.
What is radioactive decay?
Radioactive decay is a process in radioactivity in which the nucleus of atoms spontaneously breakdown or decay to produce smaller atomic nucleus with the emission of radiation.
Nuclear fusion involves the merging together of the nucleus of two or more smaller atoms to produce a larger atom whereas nuclear fission is the splitting of the nucleus of larger atoms into smaller atomic nuclei.
Therefore, the model of atoms undergoing nuclear fission will decrease in size while that of atoms undergoing nuclear fusion will increase in size.
