A carbon-12 atom has a mass defect of 0. 09564 amu. What is its nuclear binding energy? round to 3 significant figures. X 10 j per carbon-12 atom.

ur answer would be b hope i let me know if it is right

answer; i believe that the correct answer is (c) explore the outer planets; / plz check good luck

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.
