1.

In the alpha-particle scattering experiment, a few alpha particles were deflected through large angles. This shows that the nucleus is

large and diffuse
negatively charged
small, massive and charged
made of electrons
2.

Isotopes of an element have the same

nucleon number but different proton numbers
number of neutrons
mass
proton number but different nucleon numbers
3.

In β⁻ decay, the nucleus emits

an electron and an electron antineutrino
a positron and an electron neutrino
a helium nucleus
a photon only
4.

In β⁺ decay, in terms of quarks,

a down quark changes into an up quark
an up quark changes into a down quark
a strange quark changes into an up quark
no quark changes flavour

6.

Which particles are leptons?

Protons and neutrons
Pions and kaons
Quarks
Electrons and neutrinos
7.

A meson consists of

three quarks
a quark and an antiquark
three antiquarks
two leptons
8.

Alpha particles from a given nuclide have discrete energies, whereas beta particles have a continuous range of energies because

the energy is shared with an (anti)neutrino in beta decay
beta particles are slowed by air
alpha particles are heavier
beta decay does not conserve energy
9.

A nucleus of ²³⁸₉₂U emits an alpha particle. The daughter nucleus has

proton number 92 and nucleon number 234
proton number 90 and nucleon number 234
proton number 90 and nucleon number 238
proton number 91 and nucleon number 238
10.

The charge on a down quark is

−⅓ e
+⅔ e
−⅔ e
+⅓ e
