1. b
2. b
3. a
4. b
5. (a) – (iv), (b) – (v), (c) –(ii), (d) –(iii), (e) – (i).
6. 1. Conductor
   2. ductile
   3. insoluble
   4. electro
   5. dissolve.
7. The property of matter due to which it can be drawn into thin wire is called ductility. The property of metals due to which it can be beaten into thin sheet is called as malleability.
8. Metals object loose their luster after some time due to reaction with oxygen and other gases to form metal oxide. These metal oxide change the colour of the metal surface.
9. Those objects through which object can be seen but not very clearly are called translucent object. Butter paper, thick sheet of plastic are example of translucent objects. On the other hand, those objects through which light do not pass are called opaque object. Woods, bricks etc. are example of opaque objects.
10.  

    Metals	Non-metals	compounds
    Iron	Oxygen	Sodium chloride
    Gold	Carbon	water
    Sodium	Sulpher

11. Hydrogen and nitrogen are the two gases which are insoluble in water.
