Diamond is not metal, it made of carbon. And diamond can not conduct electricity, it is not malleable and ductile, so, it’s not metal.
Is Diamond a nonmetal?
Carbon is a solid non-metal element. Pure carbon can exist in very different forms. The most common two are diamond and graphite.
…
Diamond and graphite.
| Diamond | Graphite |
|---|---|
| Transparent and colourless | Opaque and black |
| Hard | Soft |
Why Diamond is a hardest non metal?
Diamond is hard due to its giant covalent lattice and it has many strong covalent bonds. The outermost shell of each carbon atom has four electrons. In these electrons are shared with four other carbon atoms to form much strong chemical bonds resulting in an extremely rigid tetrahedral crystal.
Is Diamond a lustrous non metal?
Hence, the correct answer we are looking for is both iodine and diamond are lustrous non-metals. So, the answer is D. Note: Diamond as discussed has the highest non-metallic lustre; this is also known as “adamantine”.
Is Diamond a metal material?
Diamond is the hardest naturally occurring material known.

What is the strongest metal on earth?
In terms of tensile strength, tungsten is the strongest out of any natural metal (142,000 psi).
Is Diamond a metal or stone?
Diamond, a mineral composed of pure carbon. It is the hardest naturally occurring substance known; it is also the most popular gemstone. Because of their extreme hardness, diamonds have a number of important industrial applications.
What is the world’s hardest metal?

What is the softest metal?
Cesium 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.
Is graphene harder than diamond?
Strength and stiffness
But the atoms within those layers are very tightly bonded so, like carbon nanotubes (and unlike graphite), graphene is super-strong—even stronger than diamond! Graphene is believed to be the strongest material yet discovered, some 200 times stronger than steel.
Is Diamond stronger than metal?
Are Diamonds Strong? Diamonds are one of the strongest materials on earth, but it’s not stronger than steel or several minerals.
Which metals are non lustrous?
Lead is an example of a metal which is non lustrous. Lead is a very poor conductor of electricity It is very resistant to corrosion but tarnishes upon exposure to air.
Which non metal is lustrous and shiny?
Diamond and iodine are two exceptions and are lustrous non-metal.
Are Diamonds bulletproof?
It doesn’t seem unreasonable to wonder whether diamonds are bulletproof, since diamond is the world’s hardest natural material. Diamonds are not however bulletproof in general, as while they are hard, they are not particularly tough and their brittleness will cause them to shatter when struck by a bullet.
What’s harder than diamond?
Moissanite, a naturally occurring silicon-carbide, is almost as hard as diamond. It is a rare mineral, discovered by the French chemist Henri Moissan in 1893 while examining rock samples from a meteor crater located in Canyon Diablo, Arizona. Hexagonal boron-nitride is 18% harder than diamond.
What can damage a diamond?
Sudden extreme temperature changes can cause damage, however. Diamonds can chip or fracture from hard impact, especially in areas where the carbon atoms are not tightly bonded. These areas, called cleavage planes, are the major source of damage to diamonds (figure 2).
