What is high density material?
Density is a measure of how heavy an object is for a given size, i.e.
the mass of material per unit volume.
Gold is well known for its high density – this is why people in films are often shown having difficulty carrying even one small ingot.
Lead is another familiar dense metal, used for weights and lead shot..
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.

Which has high density solid liquid or gas?
Notice that the solid (steel) is the most dense, the gas (air) is the least dense, and the density of the liquid (water) is in between.
What are the top 10 densest metals?
The 10 Densest Metals:Osmium 22.6 g/cm^3. Similar to Iridium, osmium is a hard-brittle transition metal that looks bluish-white.Iridium 22.4 g/cm^3. … Platinum 21.45 g/cm^3. … Neptunium 20.2 g/cm^3. … Plutonium 19.84 g/cm^3. … Tungsten 19.35 g/cm^3. … Gold 19.32 g/cm^3. … Uranium 18.95 g/cm^3. … More items…
What is the material density?
Material density, more often referred to simply as density, is a quantitative expression of the amount of mass contained per unit volume . … Occasionally, density is expressed in unusual units such as pounds per cubic foot, pounds per cubic inch, or metric tons per cubic meter.
What has a lot of density?

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. There’s a general trend that the volumes of the heavy atoms don’t go up as fast as the weights do, so they tend to form denser materials.
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 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.
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.
What is the densest thing on earth?
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.
Which has higher density solid or liquid?
We saw that solids and liquids have high densities because their particles are packed closely together, whereas gases have low densities because their particles are very far apart.
Is gold heavier than steel?
The problem with making good-quality fake gold is that gold is remarkably dense. It’s almost twice the density of lead, and two-and-a-half times more dense than steel.
Which liquid has lowest density?
Meaning that the densest (heaviest) liquid will be on the bottom of the jar and the least dense (lightest) liquid will be on top. The order of the liquids from heaviest to lightest will be syrup, glycerin, water, oil, and then alcohol will be on top.
Is osmium more expensive 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.
Why is osmium so expensive?
Osmium tetroxide is expensive because osmium is a rare element. Osmium is one of the rarest elements in the Earth’s crust. Osmium is obtained as a by-product from nickel and copper processing. … The US production of Os is probably only about 75 kg/year.
Which metal has highest density?
OsmiumOsmium is the densest naturally occurring element, with an experimentally measured (using x-ray crystallography) density of 22.59 g/cm3.
Which of the following has highest density?
IronIron has the highest density as the particles are closely packed and volume occupied is less which makes the density very high.
Does high density mean heavy?
Density is by definition, the amount of mass per unit volume. … Density tells scientists how “heavy” a substance is. If a substance has a higher density, it is heavier. Likewise a lighter density means it is much lighter.
What metal is bulletproof?
Created by melting aluminum around hollow metal spheres, composite metal foam is 70% lighter than sheet metal and can absorb 80 times more energy than steel. It is fireproof, radiation-resistant, and even bulletproof.
