Chemistry keyword alphabet
- 1.
- 2. A • Alloy-mixture of2 metals • Atom-smallest part of an element • Alkane- saturated hydrocarbon • Alkene-unsaturated hydrocarbon • Atomic number- number of protons in an element
- 3. B • Biodegradable-Materials thatcan be broken down by microorganisms • Biodiesel-fuel for cars made from plant oils • Biofuel-fuel made from animal or plant products • Biomass-biological material from living or recently living organisms • Blast furnace-huge reaction vessels used in industry to extract metals from ores
- 4. C • Calcium carbonate-Limestone/CaCO3 • Cement-Heated limestone and clay • Concrete-a biulding material made by mixing cement sand and aggregate • Covalent-bond between two non metals
- 5. D • Displace- reactionwhere a less reactive metal replaces a more reactive metal • Double bond- covalent bond made by the sharing of two pairs of electrons
- 6. E • Electron- tinyparticle with a negative charge, they orbit on the outer shell of an atom • Element- a substance made of one atom and found on the periodic table
- 7. F • Fossil fuels-fuel obtained from long dead biological material • Free electrons- electron that moves freely around a metal and is not held inside an atom
- 8. G • Gas- astate of matter which is made from a liquid evaporating. • Group- all elements in the periodic table are in a group from 1-7 and 0 which shows how many electrons are in the outer shell
- 9. H • Hydrocarbon- compoundcontaining only hydrogen and carbon
- 10. I • Incomplete combustion-when fuel burns in insufficient oxygen, producing carbon monoxide as a toxic product. • Ionic bond- the bond between a metal and a non metal
- 11. L • Limewater- calciumhydroxide solution • Limestone- CaCO3/ calcium carbonate • Liquid- state of matter, in between gas and solid
- 12. M • Mass number-number of protons and neutrons in an element • Mixture- when some elements or compounds are mixed together but do not react. • Monomers- small reactive molecules that react together in repeating sequence to form a chain which is called a polymer
- 13. N • Neutron- particlefound in the nucleus of an atom with a neutral charge • Nucleus- very small central part of an atom which contains neutrons and protons
- 14. O • Ore- rockwhich contains enough metal to make it economically worthwhile to extract metal • Oxsidised- a reaction where oxygen is added or when electrons are lost from a substance
- 15. P • Phtomining- theprocess of extraction of ores from metals using plants • Polymer- a substance made from very large molecules of many repeating units eg polyethene. • Polymerisation- the reaction of monomers to make a polymer • Proton- positively charged particle found in the nucleus of an atom
- 16. R • Reactivity series-a list of elements in order of reactivity, most reactive is at the top.
- 17. S • Saturated hydrocarbon-hydrocarbon with only single carbon-carbon bonds • Shell- area in atom around nucleus where electrons are found • Smelting- heating an ore to extract metal • Solid- state of matter made by freezing a liquid • Steel- alloy with small amounts of metals such as carbon
- 18. S continued • Sulfurdioxide- poisonous gas which causes acid rain. • Speed- distance moved/time taken • Stainless steel- steel which does not rust
- 19. T • Temperature- degreeof hotness of a substance • Thermal decomposition- break down of a compound by heat • Transition metal- elements from the central block of the periodic table. Have typical metal properties and form coloured compounds.
- 20. U • Unsaturated hydrocarbon-hydrocarbon with at least one carbon=carbon double bond • Unsaturated oil- plant oil with at least one carbon=carbon double bond
- 21. V • Vegetable oil-oil extracted from plants • Viscosity- resistance of a liquid to flowing/ how thick the liquid is
- 22. Ways to rememberthings • Metal licked the bond, but ionic wanted both, covalent hated metals though. • The more reactive man replaced the insensitive less reactive one!
