We know metals are widely used in our everyday life. They are an important part of our life. Metals are used in the kitchen, in making medical instruments, machinery, and infrastructure.
In this article,
we will discuss interesting facts about metals and their compounds.
Today we will know
the most amazing facts about metals and their compounds.
1. Metals make up 75% of the periodic table.
2. Aluminium is the most abundant metal in the earth’s
crust.
3. Zinc phosphide is used for killing rats.
4. Gold is the most malleable metal one gram can be
hammered into a sheet one square meter in size.
5. Zinc chloride is used in coating wood furniture.
6. Copper is one of the metals that occurs in a directly
usable metallic form.
7. Galvanized iron is coated with zinc.
8. Titanium has a high strength-weight ratio and is used
in making aerospace applications.
9. Rusting if iron increases the weight of iron.
10. `CaH_2` is called hydrolith.
11. Platinum
has a higher melting point than gold and is used in high-temperature applications.
12. Stainless
steel is a corrosion-resistant alloy and was discovered accidentally by Harry
Brearley in 1913.
13. Calcium
hydride is used in making fireproof and waterproof clothes.
14. Sliver
has the highest thermal and electrical conductivity.
15. Titanium
is called strategic metal because it is lighter than iron.
16. The
process of turning iron into steel is called alloying.
17. Group
1st elements are known as ‘alkali metals’ because its hydroxides are
alkaline.
18. The
process of coating iron with zinc is called galvanization and this prevents
corrosion.
19. Group
2nd elements are known as alkaline earth metals.
20. Mercury
is the only metal that is found in a liquid state at room temperature.
21. Chromium
oxide is known as chromic acid.
22. Tungsten
has the highest melting point(`3422℃`) of all the elements.
23. Nichrome
wire is used in electrical heaters and it is an alloy of Ni, Cr, and Fe.
24. Potassium
carbonate is known as pearl ash.
25. Selenium
is used in photoelectric cells.
26. Nickel
is used in making stainless steel.
27. Rhodium
is the rarest and most expensive precious metal.
28. Cobalt
(60 ) is used in cancer treatment.
29. Sodium
peroxide is used in submarines.
30. Barium
hydroxide is known as Baryta water.
31. Zinc
oxide is known as a flower of zinc.
32. Osmium
is the heaviest metal.
33. Silver
iodide is used in artificial rain.
34. Green
colour is due to the presence of Barium in fireworks.
35. Lithium
is the lightest metal.
36. Onion
and garlic have their specific smell due to the presence of potassium.
37. Iron
pyrites are known as fool’s gold.
38. Wrought
iron is the purest form of iron.
39. Fuse
wire is made up of lead and tin.
40. Cobalt
is used in rechargeable batteries in electric vehicles.
41. Aluminium
is highly resistant to corrosion due to the formation of an oxide layer on its
surface.
42. Mercury
is known as quicksilver.
43. Uranium
is a heavy radioactive metal.
44. Lead
oxide is known as Litharge.
45. Crimson
red colour in fireworks is due to strontium.
46. Auric
chloride (AuCl3) is used in making antivenom needles.
47. Mercury
and iron provide much resistance to the flow of electric current.
48. Transition
metals are coloured.
49. Bismuth
is a heavy metal with low toxicity and used in making stomach medicines.
50. Neptunium
and plutonium are synthetic elements.
