to include the independent and dependent variable in
your question.
what consideration do the researchers need to take in order to ensure this experiment is fair?

the volume increases

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.

the pseudoscience are like beliefs, theories, or like practices that are considered scientific
