Nuclear fission experiments show that the neutrons the uranium nuclei into two fragment
of about the same size. This process is accompanied by the emission of several:
The half-life of a certain element is 3.5 days at STP. If the temperature is doubled and
pressure is reduced to half then half-life of the same element will be:
The uranium Nucleus πππ πΌ undergoes successive decays, emitting respectively π β πππ,π° β
πππ πππ β ππππ. What is the atomic number and atomic mass of the resulting nucleus:
