Understanding Physical and Chemical Properties of Metals and Alloys

This educational resource explores the key concepts of physical and chemical properties of metals and alloys. It defines physical properties, such as ductility and conductivity, while also explaining chemical reactions and the formation of metal oxides. Key examples of metals and alloys, including bronze, brass, and steel, are provided alongside their uses. The resource also addresses the unique characteristics of alloys, highlighting their strength and structural applications compared to pure metals. Engage with these fundamental concepts of material science.

  3. Row 1, Col 1 takes place without any changes in molecular composition. 1-What is Physical Properties?

  4. 1,2 Chemical change results in one or more substances of entirely different composition from the original substances. 2.1What is chemical Reaction?

  5. 1,3 Shiny , Silver in color, Solid, Connect heat and electricity 3) Give 4 example of physical properties.

  6. 1,4 Ductility 4) The ability of a metal to be drawn into wire is a measure of its

  7. 2,1 F : Gold, Cooper 2) T or F All metals are silver in color?

  8. 2,2 T T or F 2.2 When Metals react with Oxygen it form Metal oxide.

  9. 2,3 Increase 2.3 ) Complete : The alkali metals are most reactive metals, their reactivity ----------- down the group.

  10. 2,4 K, Na, Ca, Mg, Al, Zn, Cu, Au, Ag Reorder the metals from the most reactive to least reactive Na, Au, Cu, Ag, Zn, K, Mg, Al, Ca

  11. 3,1 Is a Solid Solution mixture of two or more element, at lest one should to be metal. Define Alloys?

  12. 3,2 Bronze, Brass, Steel, Magnalium, Gold Give Example of alloy?

  13. 3,3 Spoon, building, automobiles What is the uses of Steel?

  14. 3,4 Because one alloy contain more than one type of metals atoms , So atoms slide can’t past each other. Why is Alloy harder than pure metals?

  15. 4,1 Are element that have atoms arranged in rows. Define metals:

  16. 4,2 Mg, Ca, Al, K, Na Give 5 example of Metals?

  17. 4,3 Mercury Meals is liquid at the room temperature:

  18. 4,4 Alkali Metals, Alkaline-Earth Metals, Noble Metals What do we call the metals in group1 , group 2 and group 18?
