What is the hardest and softest mineral?
Talc is the softest and diamond is the hardest.
Each mineral can scratch only those below it on the scale..
What is the only mineral that can scratch a diamond?
CorundumDiamond is the hardest mineral; no other mineral can scratch a diamond. Quartz is a 7. It can be scratched by topaz, corundum, and diamond. Quartz will scratch minerals that have a lower number on the scale….Mohs Hardness Scale.HardnessMineral9Corundum10Diamond8 more rows

What is harder obsidian or diamond?
Surprisingly, the edge of a piece of obsidian is superior to that of a surgeon’s steel scalpel. It is 3 times sharper than diamond and between 500-1000 times sharper than a razor or a surgeon’s steel blade resulting in easier incisions and fewer microscopic ragged tissue cuts.
What is the strongest thing in the world?
Graphene, which was heretofore, the strongest material known to man, is made from an extremely thin sheet of carbon atoms arranged in two dimensions.

What is the hardest rock in the world?
Diamond is the hardest known mineral, Mohs’ 10.
What is the 2nd hardest mineral on Earth?
CorundumCorundum is a very hard, tough, and stable mineral. For all practical purposes, it is the hardest mineral after Diamond, making it the second hardest mineral.
What is the softest element on earth?
According 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.
Which example lists minerals from hardest to softest?
Talc – Gypsum – Calcite – Fluorite – Apatite – Feldspar – Quartz – Topaz – Corundum – Diamond – “Mohs Scale of Mineral Hardness ” should be familiar to rock-hounds and earth-science students alike, as it lists common minerals in the order of relative hardness (talc as the softest and diamond as the hardest […]
What’s harder than a diamond?
wurtzite boron nitride(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.

Which 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 does softest mean?
