Question

What is the hardest metal on the earth?

Answer 1

Hint: We have to know that the metals are occupied in the first two rows and it has so many physical properties and chemical properties. The metals are always formed in solid state except mercury. Because mercury is the only metal which is found in the liquid state at room temperature. And it has higher density than water except sodium and potassium. Because, sodium and potassium are soft metals. When the metal is reacted with oxygen in the presence of moisture there is a formation of metal oxide.

Complete answer:
As we know that the Tungsten is the hardest metal on the earth. And it has the highest tensile strength and it exhibits a high melting point as well as high density. The tungsten is very hard to work because of its brittleness. And it is an impressive mineral which does not mix with any other metals to increase hardness. The tungsten alloys are used to prepare the heat sinks, blade, control vanes, weights and such types of other high density items. And the tungsten metals are commonly used in the automobile industry. Because it's stronger and more durable. It has the ability to resist corrosion.

Note:
We also need to know that tungsten is the hardest metal in the earth due to its tensile strength, melting point, density etc. The metal can be formed into other shapes like thin sheets or foils without breaking and cracking and this property is known as malleability. And the metals can be melted and it can be joined into thin wires and this property is known as ductility. Most of the metals are good conductors of electricity and heat and the metals are lectures. Because, it is always shining in nature.
