Which of the following characteristics of a diamond is correct?
It is a characteristic feature of diamond that it is generally found as single complete crystals which are bounded on all sides by the natural faces. In diamond, each carbon atom is bonded to four other carbon atoms by covalent bonds. This makes it super strong and so it has a high melting and boiling point.
Which of the following is correct for diamond and graphite?
So, the correct answer is “Option (C) Graphite and diamond both have giant structures.” Note: Always remember that both diamond and graphite are allotropic forms of carbon. Graphite is thermodynamically the most stable form of carbon while diamond is the kinetically most stable form of carbon.
Which of the following is the structure of diamond?
In a diamond, the carbon atoms are arranged tetrahedrally. Each carbon atom is attached to four other carbon atoms 1.544 x 10-10 meter away with a C-C-C bond angle of 109.5 degrees. It is a strong, rigid three-dimensional structure that results in an infinite network of atoms.
Which property of diamond makes it so hard?
As such each carbon atom is linked with four neighboring carbon atoms. Thus forming a rigid tetrahedral structure. It is the strong bonding that makes diamond the hardest substance.
Which diamond clarity is best?
For diamonds over 2 carats, a clarity grade of VS2 or higher is the safest bet for avoiding any signs of visible inclusions. In diamonds between 1 and 2 carats, clarity grades of SI1 or better will not have inclusions easily visible to the naked eye.
Which diamond quality is best?
FL (or Flawless) is the highest grade for clarity. An FL diamond has no imperfections even when magnified 10x by a professional. For color, D or completely colorless diamond is the highest grade. While flawless and colorless diamonds are extremely rare, cut determines a diamond’s true value.
Is Diamond a good conductor of electricity?
Most diamonds are electrical insulators and extremely efficient thermal conductors. Unlike many other minerals, the specific gravity of diamond crystals (3.52) has rather small variation from diamond to diamond.
What is the hybridization of diamond?
In diamond each carbon atom is attached to four different carbon atoms by sigma bonds. Hence, the hybridization of carbon is sp3 . In graphite each carbon atom is attached to three different carbon atoms by sigma bonds.
What is diamond and graphite?
Diamond and Graphite, both are known as the allotropes of carbon. … In these allotropes of carbon, the atoms consisting of carbon atoms in that of the Diamond and Graphite, are bound together by strong covalent bonds with different arrangements.
Does Diamond have a layered structure?
Structure and bonding
each carbon atom is joined to three other carbon atoms by covalent bonds. the carbon atoms form a hexagonal layered network structure. the layers have weak forces between them and can slide over each other.
Where is diamond found in India?
In India, Andhra Pradesh, Chhattisgarh, and Madhya Pradesh are the three states that produce diamonds. Among them, Madhya Pradesh accounts for about 90% of the total diamond resource of the country.
Is Diamond an element?
Diamond is a form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. At room temperature and pressure, another solid form of carbon known as graphite is the chemically stable form of carbon, but diamond almost never converts to it.
What stone is 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.
Which element is hardest?
The hardest pure element is carbon in the form of a diamond. Diamond is not the hardest substance known to man. Some ceramics are harder, but they consist of multiple elements.
Is Diamond heavier than steel?
Are Diamonds Stronger than Steel? … Steel is also denser than diamonds because each molecule weighs much more than a carbon atom alone. A diamond’s smoothness allows it to easier to resist wear and tear for tools such as diamond tipped drills.
