The element 218Po (Polonium-218, Z = 84, atomic mass 218.008966 u) can decay through the emission of a B-particle to 21®A+ (Astatine-218, Z = 85, atomic mass 218.00884 u). If all of the energy released is carried away by the B-particle's kinetic energy, calculate the kinetic energy of the B-particle. Give your answer in units of MeV, correct to two decimal places.

Answer:
What is the atom with the smallest atomic number that contains the same
number of electrons in all of its 's' subshells as it does in its 'd' subshell?
Note: You can refer to the relevant Figures in the Cutnell & Johnson text
book for the order in which the subshells fill up.
Select one:
Calcium (Ca)
a.
O b. Strontium (Sr)
С.
lodine (I)
