mass number
the number of protons plus neutrons in the nucleus of an atom
1 of 40
nucleus
the very small, dense, central part of an atom which contains protons and neutrons
2 of 40
neutron
a particle found in the neucleus of an atom. It is electrically neutral, carrying no charge
3 of 40
compound
the substance made when 2 or more elements are chemically bonded together
4 of 40
electron
a particle with a negative charge. The electron orbits the neucleus in atoms/ions
5 of 40
proton
a positive particle found inside the nucleus of the atom
6 of 40
shell (or energy level)
an area in an atom, around the neucleus where electrons are found
7 of 40
covalent bond
the attraction between 2 atoms that share 1 or more pairs of electrons
8 of 40
ionic bond
the electrostatic force between positively and negatively charged ions
9 of 40
calcium carbonate
the main compound found in limestone, a solid
10 of 40
thermal decomposition
the breakdown of a compound by heat
11 of 40
lime water
the common name for calcium hydroxide solution
12 of 40
calcium oxide
made when limestone is heated
13 of 40
calcium hydroxide
when water is reacted with calcium oxide
14 of 40
quarry
a hole in the ground where resources are blasted out to be used
15 of 40
ore
rock which contains enough metal to be economically worthwhile to extract the metal
16 of 40
reduction
the removal of oxygen from a compound
17 of 40
electrolysis
the breakdown of a substance containing ions by electricity
18 of 40
blast furnace
the huge reaction vessels used to extract iron from its ore
19 of 40
alloy
a metal that is mixed with other elements
20 of 40
smelting
heating a metal ore in order to extract the metal
21 of 40
transition metals
elements which are in the central part of the periodic table. They have typically metalic properties and form coloured compounds
22 of 40
phytomining
the burning of plants to extract the metal they took in whilst growing from the soil
23 of 40
distilation
separation of a liquid from a mixture by evaporation followed by condensation
24 of 40
alkAnes
a saturated hydrocarbon which has no reaction with bromine water
25 of 40
alkEne
unsaturated hydrocarbon which contains a carbon-carbon double bond ajnd turns bromine water colourless
26 of 40
fractional distilation
a way to separate liquids from a mixture of liquids by boiling the substances off at different temperatures, then condensing and collecting the liquids
27 of 40
oxidised
a reaction where oxygen is added to a sunstance (or when electrons are lost from a substance)
28 of 40
particulates
small solid particle given off from motor vehicles as a result of incomplete combustion of fuel
29 of 40
global dimming
the reflection of sunlight by tiny solid particles in the air
30 of 40
cracking
the reaction used in the oil industry to break down large hydrocarbons into smaller, more useful ones. This occurs when the hydrocarbon vapour os either passed over a hot catalyst or mixed with steam and heated to a high temperature
31 of 40
double bond
a covalent bond made by the sharing of two pairs of electrons
32 of 40
monomer
small reactive molecules that react to make one large molecule called a polymer
33 of 40
polymer
a substance made from monomers which create polymers when they react. The repeating units create a polymer, eg poly(ethene)
34 of 40
biodegradable
materials that can be broken down by microorganisms
35 of 40
fermentation
the reaction where enzymes in yeast turn yeast turn glucose into ethanol and carbon dioxide
36 of 40
emulsion
a mix of liquids that don't dissolve in each other
37 of 40
emulsifier
a substance which helps keeps imiscible liquids mixed so they don't separte into layers
38 of 40
tectonic plates
the huge slabs of rock that make up the earths crust
39 of 40
convection currents
the circular motion of matter causes by heating in fluids
