  1. Lesson #4: Metals and Non Metals Objective: Identify the metals and non metals on a periodic table and their characteristics

  2. 7.1 Using Metals Metals and non metals in the periodic table 88 of the elements are metals 21 of the elements are non metals The elements on the left of the stepped line are metals. Please draw this line on your periodic table with a black marker.

  3. Use the cards handed out to decide on the best properties for the following situations 7.1 Using Metals Find 3 essential properties of metals for water pipes • Malleable • Do not react with water or air • Strong Metal choices… …copper or lead More information: Lead is no longer used for water pipes because it can make poisonous solutions.

  4. 7.1 Using Metals Find 4 essential properties of metals for saucepans • Good conductors of heat • Do not react with water • Malleable • Strong Metal choices… …copper, aluminium or stainless steel

  5. 7.1 Using Metals Find 4 essential properties of metals for jewellery • Shiny • Hard • Malleable • Do not react with water or air Metal choices… …gold, silver, platinum

  6. 7.1 Using Metals Find 3 essential properties of metals for electrical wiring • Ductile • Good conductor of electricity • Do not react with water or air Metal choices… …copper, aluminium More information: Copper is a better conductor than aluminium

  7. 7.1 Using Metals Find 4 essential properties of metals for long-distance power cables • Ductile • Good conductors of electricity • Low density • Do not react with water or air Metal choices… …copper, aluminium More information: Copper is 3 times denser than aluminium

  8. 7.1 Using Metals Find 4 essential properties of metals for aeroplanes • Low density • Malleable • Do not react with water or air • Strong Metal choice… …aluminium More information: Aluminium does not react with water or air because it forms a protective coating on its surface

  9. 7.1 Using Metals Find 4 essential properties of metals for light bulb filaments • Ductile • Glow when hot • Very high melting points (so they don’t melt when they glow) • Good conductor of electricity Metal choice… …tungsten More information: Tungsten has the highest melting point of all metals (3410 ºC)

  10. 7.1 Using Metals Find 8 properties that most metals have • Strong • Solid at room temperature (melting point above 25 ºC) • Good conductor of electricity • Good conductor of heat • Shiny (at least when first cut) • Malleable • Ductile • Hard Write a short definition of each of the properties (pg 45 science 14 book)

  11. Non metals http://video.about.com/chemistry/Properties-of-Nonmetals.htm#

  12. - Tomorrow we will have a practical. - You will work in groups of 4. - Please bring one hammer per group of 4. - We will be in Lab 6 (Nelson’s classroom) - You must have goggles and a lab coat.
