1Rutherford suggested that [blank_start]atoms[blank_end] were mostly [blank_start]empty space[blank_end], with most of their [blank_start]mass[blank_end] in a tiny central [blank_start]nucleus[blank_end] with a [blank_start]positive[blank_end] charge and [blank_start]electrons[blank_end] moving around the [blank_start]nucleus[blank_end].

2The radius of a nucleus is approximately what size?
- A0.0000000001 m
- B0.000000000000001 m
- C0.000000000000000001 m
3The atomic number, sometimes referred to as the [blank_start]proton number[blank_end], represents the number of [blank_start]protons[blank_end] in an atom of an element.
The [blank_start]mass number[blank_end], sometimes referred to as the nucleon number, is the total number of [blank_start]protons and neutrons[blank_end] found in the nucleus of an atom.
[blank_start]Ions[blank_end] are versions of an element which have [blank_start]uneven[blank_end] numbers of protons and electrons, giving them an unbalanced [blank_start]charge[blank_end].
[blank_start]Isotopes[blank_end] are versions of an element which have different numbers of [blank_start]neutrons[blank_end], but a neutral charge.- Aproton number

4An electron is permanently fixed in a single orbit.
- ATrue
- BFalse
5All elements abide by one emission spectrum.
- ATrue
- BFalse
6In a neon tube, what type of radiation is emitted as electron fall back to their standard orbit?
- AElectromagnetic
- BNuclear
- CGaseous
7Sometimes an atom gains so much [blank_start]energy[blank_end] that one or more of the [blank_start]electrons[blank_end] can escape from the atom altogether. An atom that has lost or gained electrons is called an [blank_start]ion[blank_end]. Radiation that causes electrons to escape is called [blank_start]ionising radiation.[blank_end]

- Belectrons
- Cion
- Dionising radiation.
8AN atom has the same number of protons and [blank_start]electrons[blank_end], so overall it has no [blank_start]charge[blank_end]. If an atom loses an electron, it then has one more [blank_start]proton[blank_end] than it has electrons. It has an overall [blank_start]positive[blank_end] charge and is called a positive ion.

12Alpha particles are [blank_start]very ionising[blank_end] and can be stopped by [blank_start]a sheet of paper.[blank_end]
Beta particles are [blank_start]moderately ionising[blank_end] and can be stopped by [blank_start]aluminium 3mm thick.[blank_end]
Gamma rays are [blank_start]weakly ionising[blank_end] and can be stopped using [blank_start]lead a few cm thick.[blank_end]- Aweakly ionising

13Particles lose energy as they ionise matter.
- ATrue
- BFalse
14An unstable nucleus may lose energy as beta radiation when the subatomic particles in the nucleus are rearranged.
- ATrue
- BFalse
15Beta particles can have a negative or positive charge.
- ATrue
- BFalse
16Alpha particles can have a negative or positive charge.
- ATrue
- BFalse
17The point at which radioactive decay will occur can be predicted using half-life.
- ATrue
- BFalse
18The alarm sound in a smoke alarm is triggered when the circuit current [blank_start]decreases[blank_end].
- Adecreases
- Bincreases
19Someone is [blank_start]irradiated[blank_end] when they are exposed to alpha, beta or gamma radiation from nearby [blank_start]radioactive[blank_end] materials. Once the person moves away the [blank_start]irradiation[blank_end] stops.
Someone becomes [blank_start]contaminated[blank_end] if they get [blank_start]particles[blank_end] of radioactive material on their skin or inside their body. They will be exposed to radiation as the unstable isotopes in the material decay, and this will continue until the material has all [blank_start]decayed[blank_end] or until the source is [blank_start]removed[blank_end].

20In a nuclear [blank_start]fission[blank_end] reactor, [blank_start]control rods[blank_end] are used to manage the rate at which the chain reaction occurs. The control rods are raised if power demand is [blank_start]increased[blank_end], and are fully [blank_start]lowered[blank_end] in order to shut down the reactor.
