IV. Distinguish fission from fusion
Motivation: Demonstration [Student participation] Students will construct a magnetic model of the gold atom.
Goldfinger in Ian Fleming’s spy novel and James Bond film Goldfinger
attempted to transform the gold reserve at Fort Knox by exposing it to a
how Mr. Goldfinger’s nuclear explosion could have transformed the
non-radioactive isotope of gold to a radioactive isotope of gold?
is there no change in the chemistry of the gold?

Reactions Due to emission of radiation: Decay Reactions
Ex. Sr-90 and I-131
Ex. Tc 99 m
are nuclear reactions classified and written?

Explain why 99mTc is useful in medical science?
Estimate [in g] the mass of 99mTc after 150 minutes.
The initial mass = 2000 mg.
1/2 99mTc = 6 h. [Use interpolation and the formula to
estimate the mass of. 99mTc].
does a PETSCAN work? [Use
Power-Point to generate and explain your answer]
by means of Power-Point, including the motion picture options, explain how you
would use a PET SCAN to diagnose a brain tumor in a bottle nose dolphin.
