(amplify phase change lesson 1.3)Phase Change at the Molecular Scale Launch the Phase Change Simulation and observe different phases in the Sim. In the data table below, record your observations about the molecular scale of each phase. Consider how the movement of molecules relates to the macro-scale appearance of each phase. (I just need the molecular scale)

gold is my favorite solid.

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.
