stable
1 of 28
The work done to accelerate an electron through a potential
difference of 1V.
electon-volt
2 of 28
The process of a particle and its antiparticle colliding and being
converted into energy. The energy is released in two photons to conserve momentum

All particles have a corresponding (..) with the same mass
but opposite charge and conservation numbers
antiparticle
7 of 28
A class of hadron that is made up of a quark and antiquark pair
meson
8 of 28
The process of an electron taking in exactly the right quantity of
energy to move to a higher energy level.
excitation
9 of 28
The exchange particles that transmit the four fundamental
interactions between particles.
Gauge Boson
10 of 28
Same number of protons but different numbers of neutrons.
isotope
11 of 28
A type of meson that decays into pions.
kaon
12 of 28
A group of elementary subatomic particles, consisting of electrons,
muons and neutrinos.
lepton
13 of 28
A type of lepton that decays into electrons.
muon
14 of 28
A subatomic particle whose existence was hypothesised to maintain the conservation of energy in beta decay.
neutrino
15 of 28
The process of an atom losing an orbital electron and becoming
charged.
ionisation
16 of 28
A proton or neutron.
nucleon
17 of 28
The process of a sufficiently high-energy photon converting into a particle and its corresponding antiparticle. To conserve momentum, this usually occurs near a nucleus.
Pair Production
18 of 28
Particles that are produced through the strong interaction but
decay through the weak interaction. (..) particles
Strange
19 of 28
A type of meson and the exchange particle for the strong nuclear force
pion
20 of 28
A force that acts between nucleons in a nucleus to keep it stable. It is attractive at distances of up to 3fm and repulsive at separations less than 0.5fm. (...) Force
Strong Nuclear
21 of 28
The most stable energy level that an electron can exist in.
Ground state
22 of 28
The minimum potential difference required to stop the highest kinetic energy electrons from leaving the metal plate in the photoelectric effect.
Stopping Potential
23 of 28
The minimum energy required to remove an electron from a
metal’s surface.
Work Function
24 of 28
The minimum frequency of photons required for photoelectrons to be emitted from the surface of a metal plate through the photoelectric effect. It is equal to the metal’s work function divided by Planck’s constant. (..) frequency.
