Is osmium safe to touch?
Osmium tetroxide is highly volatile and penetrates skin readily, and is very toxic by inhalation, ingestion, and skin contact.
Airborne low concentrations of osmium tetroxide vapor can cause lung congestion and skin or eye damage, and should therefore be used in a fume hood..
How heavy is the moon?
The moon’s mass is 7.35 x 1022 kg, about 1.2 percent of Earth’s mass. Put another way, Earth weighs 81 times more than the moon. The moon’s density is 3.34 grams per cubic centimeter (3.34 g/cm3). That is about 60 percent of Earth’s density.
What is the heaviest liquid in the world?
MercuryMercury is the densest liquid at standard conditions for temperature and pressure (STP). Also called quicksilver, mercury has been known for more than 3,500 years. It is an important metal in industry, but it is also toxic.
Can osmium kill you?
Osmium Tetroxide is lethal and can be bought on the internet for less than £17 a gram, but experts say it is not as dangerous as the sarin gas unleashed on the Tokyo subway in 1995 which killed 12 and injured 6,000.
Can osmium stop a bullet?
Osmium is extremely hard, as hard or harder than the steel of the barrel you are using. … Osmium is so hard (nearly as hard as diamond) that in trying to force it into the narrower space of the rifling, you may simply shatter the bullet, because it it also very brittle.

What is osmium used for today?
Osmium has only a few uses. It is used to produce very hard alloys for fountain pen tips, instrument pivots, needles and electrical contacts. It is also used in the chemical industry as a catalyst.
Is osmium rarer than gold?
Funnily enough, Os is considered as a platinum group metal. Additionally it is much rarer than gold, about 1000 times. … Interestingly, being about 1000 times rarer than Gold. Osmium is still not as expensive as Gold, being around $400 USD per ounce compared $1,300 USD per ounce.
Which is the rarest metal?
franciumThe rarest stable metal is tantalum. The rarest metal on earth is actually francium, but because this unstable element has a half life of a mere 22 minutes, it has no practical use.

Is osmium stronger than diamond?
In a surprising overturn, the lustrous, blue-white element osmium has beaten diamond in a test of compressibility. Not used much today, osmium has been incorporated into alloys for fountain-pen tips and phonograph needles. Diamond still reigns as the hardest of materials.
Is Lead heavier than gold?
Different materials have different densities. For example, the mass density of gold is 19.3 g/cc, lead is 11.4 g/cc, copper is 9.0 g/cc, aluminum is 2.7 g/cc, water is 1.0 g/cc (1g/cc = 1 gram per cubic centimeter). … Gold is much heavier than lead. It is very dense.

How heavy can a human get?
As the heaviest person ever recorded weighed in at approximately 1,400 lbs., one could conclude that this could be close to the maximum possible. On the other hand, if a reasonably healthy individual were to attempt to break this record, it is conceivable to gain 25 lbs. a week, for a possible gain of 1350 lbs.
What is the densest substance known to man?
element osmiumAt 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. Even osmium is full of fluff, however, in the form of electron clouds that separate the dense atomic nuclei.
