PART D. Write the complete nuclear transmutation equation of the following instances.
1. What element will be produced if Tungsten-184 is bombarded with deuterium?
2. What element will be produced if Zirconium-91 undergoes alpha decay?
3. Mercury-201 undergoes electron capture, what element will be produced?
PART E. Write T if the statement is TRUE or F if the statement is FALSE.
1. Alpha decay causes the mass of an atom to decrease by 4.
2. Positron decay causes a neutron to change into a proton.
3. Gamma decay has no significant effect on the mass of a nucleus.
