Kylie has two glasses with equal volumes of pure water. She adds 40 g of sugar to one of the glasses of water and 40 g of salt to the other. When sugar is dissolved in water, it does not change the number of ions present. When salt is dissolved in water, however, the number of ions significantly increases. Which of the following is true about the electrical conductivity of Kylie's two solutions?

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.
