. A polonium-210 nucleus is formed when a stationary nucleus of bismuth-210 decays.
A beta-minus (β−) particle is emitted in this decay.
Outline, with reference to β− decay, why bismuth-210 and polonium-210 have different
proton numbers.

The kinetic energies of β− particles emitted from a sample of bismuth -210 are box
analysed. These β− particles have a range of kinetic energies.
The total energy released when each nucleus of bismuth -210 decays to a
nucleus of polonium-210 is 1.2 MeV.
Figure 1 shows the variation with Ek of the number of β− particles that have the kinetic
energy Ek.
Figure 1
. Explain how the data in Figure 1 support the hypothesis that a third particle is
produced during β− decay.
