21/02/2021 Atoms and Elements Try the following mini quiz!! Answer the questions on paper and then check the answers. Good luck!

21/02/2 021 Watch the following video about ‘Ferocious Elements’ http: //www. tes. co. uk/teachingresource/Teachers-TV-KS 3 -4 -Science. Periodic-Table-6047945/

21/02/2021 Elements and symbols that you should know: Part 1 – The obvious ones: 1) Hydrogen H 8) Oxygen O 2) Helium He 9) Fluorine F 3) Lithium Li 10) Neon Ne 4) Beryllium Be 11) Magnesium Mg 5) Boron B 12) Aluminium Al 6) Carbon C 13) Silicon Si 7) Nitrogen N 14) Phosphorus P

21/02/2021 Some more obvious ones: 15) Sulphur S 18) Calcium Ca 16) Chlorine Cl 19) Zinc Zn 17) Argon Ar The less obvious ones: 1) Sodium Na 6) Tin Sn 2) Potassium K 7) Gold Au 3) Iron Fe 8) Mercury Hg 4) Copper Cu 9) Lead Pb 5) Silver Ag

21/02/2021 We are now going to look at the properties of metals and non-metals A copy of the metal fact file sheet is included as a word document.

Which are metals? Which are non-metals? Diamond Mercury Graphite Titanium Polypropylene Silicon Iron Calcium

Properties of metals: Solids at room temperature Good electrical conductors Strong Shiny Good heat conductors Flexibleductile and malleable

Properties of non-metals Good heat insulators Dull Brittle Often gases/liquids or solids that melt easily Good electrical insulators

Examples of non metals Gas at room temp Melts at a low temp Sulphur Oxygen Brittle Gas at room temp Glass Chlorine

Examples of metals: Magnetic Great conductor of heat and electricity Shiny, strong and malleable Shiny

Why is mercury unusual? !!! http: //www. youtube. com/watch? v=1 xc 0 SMMCs 08

21/02/2021 Using the slides you have just read fill in the table using the words below about the properties of metals and non-metals Metal dull Non metal strong Malleable (bendy) Ductile (drawn into wires) Sonorous (makes magnetic a sound when hit) Conducts heat/electricity shiny High density brittle Low density

21/02/2021 Research task!! v Choose a metal (on the left of the zigzag on the periodic table v Find out about the discovery of the metal – when? where? Who? v Find out about the properties of the metal – Boiling point? Melting point? Atomic number? Mass number? colour? Density? Magnetic? Conductivity? Hard/soft? v Find out about the uses of the metal v Make a poster of your chosen metal including pictures and diagrams and colour. v You can do this on paper or on the next powerpoint slide.
