What minerals rate a value of 9-10 on the mohs scale?
On the Mohs scale of mineral hardness, the minerals that rate a value of 9-10 include corundum, which encompasses sapphires and rubies at a hardness of 9, and diamond, which is rated at 10. Corundum is known for its toughness and is used in abrasives, while diamond, being the hardest known natural material, is prized in jewelry and industrial applications for its cutting ability.
The standard scale against which the hardness of minerals is rated?
The standard scale used to rate the hardness of minerals is called the Mohs scale. It ranges from 1 (softest) to 10 (hardest), with each number representing a mineral that can scratch all those below it. Talc is the softest mineral with a rating of 1, while diamond is the hardest with a rating of 10.
What does the MERV scale measure?
The MERV scale, also known as the Minimum Efficiency Reporting Value, measures the rate of effectiveness of air filters. MERV was designed in 1987 and has been in use since than.
What is the hardness of neon on Mo Scale?
The scale you seek is Mohs' scale and applies only to solids. Mohs devised this scale about 1812 where talc is 1, gypsum is 2 up to diamond 10. Neon gas would not come under this scale.Adrian
If an iron nail is harder than gypsum and softer than calciteapproximately what hardness might it rate?
An iron nail typically has a hardness of around 4 to 5 on the Mohs scale. Gypsum rates at about 2, while calcite is around 3. Therefore, since the iron nail is harder than gypsum and softer than calcite, it would likely rate closer to 4.
How hard is protactinium on mohs scale?
Very probable the hardness of protactinium was not measured up today because is very difficult to obtain a sufficient sample.
What minerals rate a value of 9-10 on the mohs scale?

What is the hardness of potassium on moh's hardness scale?
There are a number of hardness scales used in modern science. The Moh's hardness scale measures the ability of one sample to scratch another. This is still often used to identify minerals especially by amateurs. Moh's suffers from some some inadequacies, for example one crystal face may be harder than another in a given sample. Metals such as potassium are more often rated on other scales, for example Rockwell or Brinell hardness tests which measure the ability of a diamond point to indent the sample. The Wikipedia page for Potassium gives the moh's hardness as 0.4 however.
Why does selenite gypsum become rounded at a a fast rate when tumbled along a stream bottom?
Gypsum is a soft stone. It only has 2 on the Mohs Hardness Scale. Anything harder than it will polish it.
What does californium rate on the hardness scale?
Californium is a synthetic element that is not typically rated on the traditional hardness scale due to its radioactive and unstable nature. It is primarily used for research purposes and is not known for its physical properties like hardness.

What is the scale scientists curentally use to rate an earthquake?
the Richter scale
What scale was developed to rate earthquakes according to the level of the damage?
The Richter Scale.
What risks are involved with Mohs surgery?
Mohs surgery provides high cure rates for malignant skin tumors. For instance, the five-year cure rate for basal cell carcinoma treated by Mohs surgery is higher than 99%. The frequency of recurrence is much lower with Mohs surgery is much lower
