What is the hardest mineral to break?
For example the diamond is the hardest mineral because no other mineral on the scale is able to scratch it..
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.

What is the softest element?
CesiumCesium is considered the softest metal, Lead is also considered among the softest metals. Answer 3: Mercury is liquid (molten) at room temperature. Gallium, while solid (if soft) at room temperature, is liquid at body temperature.
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.”
Which element is hardest?
The Hardest Metals in the WorldTungsten (1960–2450 MPa) Tungsten is one of the hardest metals you will find in nature. … Iridium (1670 MPa) Like Tungsten, Iridium is a chemical element that shows signs of high density and a tolerance of high temperatures. … Steel. … Osmium (3920–4000 MPa) … Chromium (687-6500 MPa) … Titanium (716 to 2770 MPa)
What is the strongest mineral in the world?
1. Diamond. Diamond is the hardest known natural mineral according to the Mohs scale. Its hardness depends on its purity, and the hardest diamond can only be scratched by other diamonds.
What can scratch a diamond?
Yes, it’s true, diamonds are the hardest substance on earth, and can only be scratched by other diamonds. But if you’re doing the scratch test where you rub it against another stone or with sandpaper and it’s not a diamond, you’re only going to ruin the stone you’re scratching!
Which is the softest mineral found inside the Earth?
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.
