What is the hardest softest natural substance?
The hardest substance known is diamond.
[but see note below] Diamond is made up entirely of the element carbon.
(Another thing that is made entirely of carbon is graphite, one of the softest substances.) Diamond’s hardness is roughly 10.5-14.5 million psi..
What is the rarest mineral?
PainiteThe Guinness Book of World Record called Painite the world’s rarest mineral. It was discovered in Burma in 1951 by a British gemologist Arthur Charles Davy Pain and for decades, only two specimens were known to exist.
What is the strongest thing on earth?
grapheneCase in point: graphene. Graphene, which was heretofore, the strongest material known to man, is made from an extremely thin sheet of carbon atoms arranged in two dimensions.
Is Bedrock harder than diamond?
In our universe, diamond has a hardness of 10 on the Mohs scale. … Bedrock can be made from many different substances, with a hardness anywhere from 1 to 9. So even the hardest bedrock is still not as hard as diamond.
Is water the softest thing in the world?
“Water is the softest thing, yet it can penetrate mountains and earth. This shows clearly the principle of. softness overcoming hardness.”

What is the softest rock in the world?
talcThe name for talc, a sheer white mineral, is derived from the Greek word talq, which means “pure.” It is the softest rock on earth.
What is the softest known material?
TalcTalc is the softest mineral on Earth. The Mohs scale of hardness uses talc as its starting-point, with a value of 1. Talc is a silicate (like many of the Earth’s most common minerals), and in addition to silicon and oxygen, contains magnesium and water arranged into sheets in its crystal structure.
Is Titanium stronger than a diamond?
Titanium is not stronger than a diamond. In terms of hardness, Titanium is not harder than a diamond either. … The only advantage titanium has over steel is that it is a much lighter material. When compared to diamond, however, titanium does not come close in strength or hardness.
What is the weakest rock?
Sedimentary rocksSedimentary rocks tend to be the ‘weakest’ of the three, as Igneous and Metamorphic rocks both undergo extreme pressures to form.
What is the strongest rock in the world?
Hard – cannot be scratched by a knife but can scratch glass, Mohs’ 6-9; Diamond is the hardest known mineral, Mohs’ 10.

What is the softest material known to man?
talcAccording to the Mohs scale, talc, also known as soapstone, is the softest mineral; it is composed of a stack of weakly connected sheets that tend to slip apart under pressure. When it comes to metals, scientists try to measure hardness in absolute terms.
What mineral smells like rotten eggs?
Hydrogen sulfide smells like rotten eggs. Most sulphur on Earth is found in sulfide and sulfate minerals.
Which is the softest metal in the world?
Cesium is a rare, silver-white, shiny metal with brilliant blue spectral lines; the element’s name comes from “caesius,” a Latin word meaning “sky blue.” It is the softest metal, with a consistency of wax at room temperature.

What is the most expensive metal on earth?
PalladiumPalladium is the most expensive of the four major precious metals – gold, silver and platinum being the others. It is rarer than platinum, and is used in larger quantities for catalytic converters.
What is the hardest metal in the world?
tungstenIn terms of tensile strength, tungsten is the strongest out of any natural metal (142,000 psi). But in terms of impact strength, tungsten is weak — it’s a brittle metal that’s known to shatter on impact. Titanium, on the other hand, has a tensile strength of 63,000 psi.
What’s harder than diamond?
boron nitrideThe structure of boron nitride in its wurtzite configuration is stronger than diamonds. Boron nitride can also be used to construct nanotubes, aerogels, and a wide variety of other fascinating applications.
Which is the hardest thing in the world?
(PhysOrg.com) — Currently, diamond is regarded to be the hardest known material in the world. But by considering large compressive pressures under indenters, scientists have calculated that a material called wurtzite boron nitride (w-BN) has a greater indentation strength than diamond.
