Which is more dense iron or osmium?
Answer 1: Osmium is the most dense metal!
How much dense is osmium?
Osmium is the densest naturally occurring element. When experimentally measured using x-ray crystallography, it has a density of 22.59 g/cm3.
How much does a gram of osmium weigh?

Is osmium the heaviest metal?
Osmium is one of the heaviest materials on earth, weighing twice as much as lead per teaspoon. Osmium is a chemical element in the platinum group metals; it’s often used as alloys in electrical contacts and fountain pen nibs.
Why is osmium so dense?
The very small atomic radius of osmium results in a small metal-metal separation. This small atomic separation along with osmium’s relatively high atomic number gives rise to osmium’s high density.
Is there anything denser than osmium?
At room temperature and pressure, the calculated density of osmium is 22.61 g/cm3 and the calculated density of iridium is 22.65 g/cm3. At room temperature and a pressure above 2.98 GPa, iridium is denser than osmium, with a density of 22.75 grams per cubic centimeter.
What is the weight of osmium?
190.23 u
Osmium/Atomic mass
Which metal is the least dense?
lithium
Under standard conditions, lithium is the lightest metal and the least dense solid element. It is a soft, silver-white metal belonging to the alkali metal group of chemical elements.
What is the density of osmium in kg m3?
Having reviewed crystallographic data for both osmium and iridium, selected values of their densities at a temperature of 20°C are 22,590 kg/m3 and 22,560 kg/m3, respectively, thus confirming that osmium is the densest metal.
Is osmium denser than diamond?
Researchers from us-based Lawrence Livermore National Laboratory (llnl) have discovered that osmium, a metal, is harder than diamond. It withstands compression better than any other material. The researchers found that osmium has a bulk modulus that is about five per cent higher than diamond.
Can you melt osmium?
Osmium is a bluish-white, shiny metal with a melting point of about 3,000°C (5,400°F) and a boiling point of about 5,500°C (9,900°F). Its density is 22.5 grams per cubic centimeter. It cannot be melted and shaped like most metals. Because it is unworkable, it has very few practical uses.
Is osmium the densest metal?
Reviews by Crabtree ( 1) and the present author ( 2 – 5) established that at 293.15 K (20°C) osmium is the densest metal at 22,589 ± 5 kg m –3 compared to 22,562 ± 11 kg m –3 for iridium, the difference of 27 ± 12 kg m –3 considered as confirming this.
Are osmium and iridium heavier than plutonium?
However, if you go by a practical metric, like the weight of a brick of a material you might think otherwise. Osmium and iridium are very dense materials ~22.6 g/cm 3 — about 20 times heavier than the same volume of water and about 10\% more dense than plutonium. They would seem to be heavier, but the atoms are actually lighter.
How much does a liter of osmium weigh?
Many people are familiar with lead (11.3 kg/L), but osmium is twice as dense (22.6 kg/L)! Each liter (about 1/4 gallon) of osmium weighs 22.6 kg (50 lbs). For comparison, each liter of water weighs only 1 kg (~2.2 lbs).
Why does osmium have such a small atomic radius?
Osmium’s 6s orbital (its outermost orbital) is consequently contracted, so overall osmium’s size (atomic radius) is reduced. Look here and notice how osmium’s radius sticks out like a sore thumb. Its radius is by far the lowest for its atomic number.
