Question 1
What value of
Z (atomic number) and
A (mass number) result in the following
β-decay?

◦
Z = 6; A = 12
◦
Z = 5; A = 8
◦
Z = 6; A = 11
◦
Z = 8; A = 12
◦
Z = 8; A = 11
Question 2
When a neutron decays, a proton and an electron are observed. When the electrons emitted from a sample of neutrons are observed, they are found to have different kinetic energies. This was accounted for by
◦
introducing a different particle, the neutrino.
◦
introducing the effect of gravity on the particles.
◦
including the kinetic energies of the neutron and proton.
◦
modifying the laws of conservation of momentum and energy.
◦
taking into account the uncertainties associated with Heisenberg's Uncertainty Principle.
