Answer 1

Part A)

A radioactive decay series is a sequence of radioactive decays that occur when a very heavy radioactive atom, such as uranium, undergoes radioactive decay to produce a daughter nuclide that is also radioactive. Each daughter nuclide in the series also undergoes radioactive decay until, after many decay steps, a hellium is formed.

Part B)

The nuclear fission reaction is triggered by a neutron colliding with a fissionable nuclide which produces lighter elements and more neutrons. The neutrons produced in the reaction can then collide with other nuclides producing a chain reaction. This reaction can be used to make a bomb, because a tremendous amount of energy is released during each fission reaction!
