Edexcel Physics P3: Particles in Action Key Words

Key WordDefinition
Absolute ZeroThe lowest temperature that is theoretically possible, at which particles have no kinetic energy.
Accelerating AnodeTakes the electrons produced by a cathode and accelerates them before they are fired.
Alpha ParticleA +2 charged helium nucleus emitted by some radioactive substances.
Beta ParticleA fast-moving electron emitted by radioactive decay of substances
CathodeThe positively charged electrode of an electrical device, such as a primary cell, that supplies current.
CelsiusA scale of temperature in which water freezes at 0° and boils at 100° under standard conditions.
DecayTo undergo change to a different form by emitting radiation.
Electron BeamA stream of electrons in a gas or vacuum.
Fundamental ParticleA minute portion of matter which as far as we know cannot be broken down further.
Gamma RadiationHighly penetrating electromagnetic radiation.
IsotopeEach of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.
KelvinA scale of temperature with absolute zero as zero.
Kinetic EnergyEnergy possessed by objects that are in motion.
NeutronA subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen.
NucleusThe positively charged central core of an atom that contains most of its mass.
OscilloscopeA device for viewing oscillations by a display on the screen of a cathode ray tube.
Particle AcceleratorApparatus for accelerating subatomic particles to high velocities by means of electric or electromagnetic fields.
ParticleA particle smaller than an atom (e.g., a neutron) or a cluster of such particles (e.g., an alpha particle) .
PositronA subatomic particle with the same mass as an electron and a numerically equal but positive charge.
PressureThe continuous physical force exerted on or against an object by something in contact with it
ProtonA stable subatomic particle occurring in all atomic nuclei, with a positive electric charge.
QuarkAny of a number of subatomic particles carrying a fractional electric charge, postulated as building blocks of the hadrons.
RadiationEnergy emitted from a source
RadioactiveEmitting or relating to the emission of ionizing radiation or particles.
TemperatureThe degree or intensity of heat present in a substance or object
Thermionic EmissionThe emission of electrons from a heated source.

Edexcel Chemistry C3: Chemical Detection Key Words

Key WordDefinition
acidA chemical substance (typically, a corrosive or sour-tasting liquid) that neutralizes alkalis, dissolves some metals, and turns litmus red.
anionA negatively charged ion, i.e., one that would be attracted to the anode in electrolysis.
Avogadro's lawOne mole of any gas occupies 24dm3 at room temperature (25oC)
baseA substance capable of reacting with an acid to form a salt and water, or (more broadly) of accepting or neutralizing hydrogen ions
cationA positively charged ion, i.e., one that would be attracted to the cathode in electrolysis
flame testA procedure used in chemistry to detect the presence of certain metal ions, based on each element's characteristic emission spectrum.
indicatorA dye that changes colour depending on whether it's above or below a certain pH
ionAn atom or molecule with a net electric charge due to the loss or gain of one or more electrons
ionic substanceForms giant ionic lattices containing oppositely charged ions.
molar volumeThe molar volume, symbol Vm, is the volume occupied by one mole of a substance
moleThe name given to a certain number ( 6.023 x10^23 )
precipitationPrecipitation is the formation of a solid in a solution or inside another solid during a chemical reaction or by diffusion in a solid. When the reaction occurs in a liquid, the solid formed is called the precipitate.
purityThe state or degree of being pure
qualitativeQualitative analysis tells you if a particular substance is present; but not how much of it there is.
quantitativetells you how much of a particular substance is present.
reactantA substance that takes part in and undergoes change during a reaction
titrationused to find out concentrations
