Structure can affect the Ka values for related acids. In the boxes below, draw the complete Lewis structure for a single ion of the conjugate base of each acid after the removal of a proton and consider the change in stability of the ion resulting from deprotonation. HINTS: Consider any increase/decrease in ability to participate in intramolecular hydrogen bonding as well as how the resulting –COO- groups in a molecule will interact with other atoms in the same molecule/ion.

the answer is alpha particles hope i you

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.
