Which aspect must be taken

Question

into consideration when
creating a model of
radioactive decay? (1 point)
There must not be any
changes to the
element in question.
There must not be any
particles or energy
emitted from the
nucleus.
There must be a
predictable and
reversible change that
occurs.
There must be a way
for unstable nuclei to
become stable nuclei.

Answer 1

The aspect that must be taken into consideration when creating a model of radioactive decay is:

There must be a way for unstable nuclei to become stable nuclei.

This is fundamental to the concept of radioactive decay, which involves unstable isotopes transforming into stable ones, either by emission of particles or radiation.
