talc is the softest substance while daimond is th4e hardest substance on earth
Talc can scratch Talc , although Talc's hardness varies it is considered a soft mineral, that can even be scratched with a finger nail. Any mineral or material with a hardness equal to or greater than 1 on the Mohs hardness scale will be able to scratch talc. Talc is the softest mineral listed on the Mohs scale, listed as a 1 on the scale which is graded from 1 through 10, with 10 being the hardest (diamond).
Talk about Talc!
Talc is mildly basic, with a pH of ~9.
a blue diamond! :P GEMUSE!! maybe a saphire.
it is a geological scale that measures the hardness of different minerals. Talc being the softest and a diamond being the hardest.
the softest rock is talc and the hardest is a diamond
No.
The diamond is the hardest substuance on the MHos Scale and Talc is the softest.
Diamond is the hardest mineral known.
The hardest mineral is diamond, and the softest mineral is talc.
talc is the softest rock in the world while diamond is the hardest rock
No. Talc is the softest mineral. It can't scratch anything that is harder that itself. Talc is number 1 on the Mohs scale, a scale of hardness, but diamond is number 10, which means that diamond is very much the harder of the two. You can't even scratch a diamond with a fingernail, hardness of about 2.5, so talc with even less hardness doesn't stand a chance against the mighty diamond!

A diamond and talc
No real size difference is important. A tiny diamond is still a diamond.
A diamond and talc
No. On the Mohs Scale of hardness, the hardness comparisons are exactly opposite. Talc is rated as 1 -- soft, and diamond is rated as 10 -- hard, in fact, the hardest rating.
Talc is the mineral with a hardness of 1 on the Mohs scale.
