What makes diamonds so strong and graphite so brittle and breakable?
It is the structure of the combination of carbon atoms. In diamond , each carbon atom combines tetrahedrally with dour adjacent carbons atoms. This gives it a very hard and rigid structure. In graphite each carbon atom combines hexagonally with three adjacent carbon atoms , leaving a 'free' electron in uncombined form . This gives graphite a softer structure, which can slide over each other as sheets of carbon atoms.
How many rigid parts are in acetylsalicylic acid?
There are two: the c double bonded to o parts and the ring structure.
Why does graphite feels greasy but diamonds don't?
in graphite the layers of carbon atoms slide over eachother making it feel greasy in the case of diamong the rigid structure prevents any movement
Why peptide bond is rigid and planar?
rigid because of the resonance stabilization of the amide (peptide) bond and the C=O (C double bond O) cause the structure to be planar and is therefore incapable of rotation.
When is lonsdaleite softer than a diamond?
Lonsdaleite is formed within meteorites and found when the meteorites land on earth. This is another alltrope of carbon, but with a different -- Hexagonal dihexagonal dipyramidal -- crystal structure. It is always softer than a diamond, because a diamond's crystal structure maximizes the carbon's valance -- four -- into its rigid tetrahedral network of covalent bonds on eight sides.
What is the difference between a structure that is rigid and one that is flexible?
The difference between a structure that is rigid and one that is flexible is that the rigid structure will not bend or flex when force is applied. A structure that is rigid cannot flex.
Why diamond has higher melting point?
Usually non-metals do not have high melting point , but there are some exceptions also and diamond is one them.Diamond is an allotrope of carbon.Structure of diamond is regular tetrahedron. Carbon atoms in diamond are powerfully bonded.The outermost shell of every atom becomes stable.Due to this the structure becomes very rigid which makes the Diamond one of the hardest substances. ___________ANKIT TOMAR
Identify the structures that comprise an animal cell?
An animal cell's structure is flexiable while a plants cell's structure is rigid
What name is given to the rigid structure found outside the plasma membrane that surrounds and supports the bacterial cells?
The cell wall is a rigid supporting structure.

What kind of bond and structure is a diamond?
Tetrahedrally linked carbon atoms that are connected via single sigma bonds. The cross linked nature of the bonds makes it so strong and rigid.
How many rigid parts are in acetylsalicylic acid?
There are two: the c double bonded to o parts and the ring structure.
A plant cell has a structure that keeps its shape very rigid What structure has this purpose?
Cell wall
How any atoms are a diamond?
Diamond is pure, crystalline Carbon. It is one of the hardest natural substances known, and attributes it's hardness to an isometric octahedra crystalline structure which is very rigid and tough.
Why does graphite feels greasy but diamonds don't?
in graphite the layers of carbon atoms slide over eachother making it feel greasy in the case of diamong the rigid structure prevents any movement
What is a rigid structure surrounding the cell memebrane?
cell wall
Why are brains squishy?
Because they are 80% water and have no rigid structure
