What is the softest metal?
CesiumCesium is a rare, silver-white, shiny metal with brilliant blue spectral lines; the element’s name comes from “caesius,” a Latin word meaning “sky blue.” It is the softest metal, with a consistency of wax at room temperature..
What is the lightest metal on earth?
lithiumLightest Elemental Metals The lightest or least dense metal that is a pure element is lithium, which has a density of 0.534 g/cm3. This makes lithium nearly half as dense as water, so if lithium was not so reactive, a chunk of the metal would float on water.
What’s harder than a diamond?
(PhysOrg.com) — Currently, diamond is regarded to be the hardest known material in the world. But by considering large compressive pressures under indenters, scientists have calculated that a material called wurtzite boron nitride (w-BN) has a greater indentation strength than diamond.
Can graphene stop a bullet?
Graphene: The Miracle Material That’s As Light As Foil, But Can Stop A Bullet. … Despite graphene being remarkably thin, it’s strong enough to protect from a bullet, according to a statement describing the new research.
Is Titanium stronger than steel?
Titanium is highly valued in the metals industry for its high tensile strength, as well as its light weight, corrosion resistance, and ability to withstand extreme temperatures. It’s as strong as steel but 45% lighter, and twice as strong as aluminum but only 60% heavier.
Is Diamond stronger than steel?
Diamond is much harder than steel and has a much higher compressional strength, but is much more brittle than steel. … Although steel is hard, it is still much worse than diamonds. Nonetheless, diamonds cannot be used to cut steel or cutters because diamonds are made of carbon and carbon is soluble in steel.
Which is the lightest matter?
Aerographene, also known as graphene aerogel, is believed to be the world’s lightest material with a density of just 0.16 milligram per cubic centimeter. Zhejiang University researchers developed the material, which is approximately 7.5 times less dense than air.

Is Titanium stronger than diamond?
Titanium is not stronger than a diamond. In terms of hardness, Titanium is not harder than a diamond either. … Diamond strength is around 60 GPa. As for the hardness scale, titanium is 36 Rockwell C, while diamond is 98.07 Rockwell C.
What is the world’s strongest metal?
tungstenIn terms of tensile strength, tungsten is the strongest out of any natural metal (142,000 psi). But in terms of impact strength, tungsten is weak — it’s a brittle metal that’s known to shatter on impact. Titanium, on the other hand, has a tensile strength of 63,000 psi.
What is the heaviest material on earth?
OsmiumOsmium 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.
Is Iron stronger than gold?
Gold has many more protons and neutrons in the nucleus of each atom than iron does. So each gold atom weighs almost four times as much as each iron atom. … So gold ends up denser.
What is the lightest strongest material?
grapheneA team of MIT researchers have created the world’s strongest and lightest material known to man using graphene. Futurism reports: Graphene, which was heretofore, the strongest material known to man, is made from an extremely thin sheet of carbon atoms arranged in two dimensions.
Is Titanium more expensive than gold?
No, titanium is not more expensive than gold. The problem with titanum is the hardness. Titanium is very hard. … Both would be hard on gold but titanium held up very well.
What liquid is lightest?
The order of the liquids from heaviest to lightest will be syrup, glycerin, water, oil, and then alcohol will be on top.
Is it safe to play with gallium?
Gallium is a silvery metal and element number 31 on the Periodic Table, and it melts at 85.6 degrees Fahrenheit. That’s a temperature low enough for gallium to melt in your hand — and unlike the liquid metal mercury, gallium is safe to play with, according to chemists.
What metal is the rarest?
RhodiumFacts About Rhodium. Rhodium is a silver-white metallic element that is highly reflective and resistant to corrosion. It is considered the rarest and most valuable precious metal in the world — well above gold or silver.
