AnswersDriveOsmium
Also, what is the world's densest material?
At the modest temperatures and pressures of Earth's surface, the densest known material is the metallic element osmium, which packs 22 grams into 1 cubic centimetre, or more than 100 grams into a teaspoonful.
What is the densest natural metal?
It is a hard, brittle, bluish-white transition metal in the platinum group that is found as a trace element in alloys, mostly in platinum ores. Osmium is the densest naturally occurring element, with a density of22.59 g/cm3.

What is the most dense rock on Earth?
Even though it is relatively thin it is Page 2 the densest type of crust (3.0 g/cm3) and is made up of a metamorphic rock called basalt. Continental crust makes up the continents and rests on top of oceanic crust. Continental crust consists of less dense rock such as granite.

How dense is a black hole?
A black hole generally forms after a star dies in a titanic explosion known as a supernova, which crushes the remaining core into dense lumps. A maddening enigma called a singularity -- a region of infinite density -- lies at the heart of each black hole, according to general relativity, the modern theory of gravity.

How dense is a diamond?
Diamond is a crystalline form of carbon which has a density of has a density of 3.51 gm/cm3 compared to 2.26 gm/cm3 in the graphite form. Imperfectly formed crystalline forms of diamond are called bort and black diamond. They are slightly less dense than diamond and are somewhat tougher and harder.

Who created osmium?
Osmium was discovered in 1803, in London, by English chemist Smithson Tennant. He also discovered iridium in the same year. Earlier in his career, Smithson Tennant had established that diamond is pure carbon.

What Colour is lead?
Lead (/l?d/) is a chemical element with atomic number 82 and symbol Pb (from Latin: plumbum). It is a soft, malleable, and heavy metal. Freshly cut solid lead has a bluish-white color that soon tarnishes to a dull grayish color when exposed to air; as a liquid, lead has a shiny chrome-silver luster.

What is the metal with the highest melting point?
Tungsten objects are also commonly formed by sintering. Of all metals in pure form, tungsten has the highest melting point (3422 °C, 6192 °F), lowest vapor pressure (at temperatures above 1650 °C, 3000 °F), and the highest tensile strength.

Is osmium rare?
Osmium is a rare metallic element from the Platinum Group Metals (PGMs) and is a transitional metal. It is the densest metal with a very high melting point, it is also hard but brittle and has a low vapour pressure. Did you know? Osmium has a lower compressibility than diamonds.
11
How expensive is osmium?
Osmium is usually sold as a minimum 99.9% pure powder. Like other precious metals, it is measured by troy weight and by grams. Its price in 2012 was about US$400 per troy ounce (or about $13,000 per kilogram), depending on the quantity, its purity and its supplier.
12
What is the hardest metal on earth?
The hardest metal is chromium.Actually, hardness is determined by the resistance of the material to be scratched . The hardest material is diamond,then comes corundum etc.This hardness is measured on Mohs scale.People get confused that Osmium has the better claim, but actually it is the densest .
14
Why Osmium is so dense?
Osmium is the most dense element because it has the most mass in the smallest amount of space. Density is mass divided by volume. An element with more neutrons will be denser, because neutrons have roughly the same mass as a proton.
15
How much does the heaviest thing on Earth weigh?
According to the Guinness Book of World Records, the heaviest thing to ever be weighed as of 2015 was the Revolving Service Structure of launch pad 39B at the Kennedy Space Center in Florida. It weighed 2423 tonnes, or 5,342,000 pounds, and required 21 jacking points to lift.
16
What is the most dense liquid in the world?
The Densest Liquid. Mercury measures 13.534 grams per cubic centimeter. That's thirteen and a half times more dense than water, which scientists have assigned a density of 1.0.
17
What is the densest known material in the universe?
The densest objects in the Universe. When a massive star explodes, not all the material is ejected into space. Some of it collapses into an extremely compact object known as a neutron star, inside which gravitational forces crush protons and electrons together, turning them into particles known as neutrons.
18
Which is the heaviest metal?
I assume by "heaviest," you mean "densest;" in that case, the densest chemical element is osmium (which is a metal). Osmium has a density of around 22 grams per cubic centimeter, about twice the density of lead! Answer 3: The heaviest naturally occurring element is plutonium measured by the mass of the element.

Where can osmium be found in the world?
Osmium occurs in iridosule and in platinum-bearing river sands in the Urals, North America, and South America. It is also found in the nickel-bearing ores of Sudbury, Ontario region along with other platinum metals.
