Silicon dioxide diamond covalent network?
Not sure what that means... but both silicon dioxide (sand) and diamond are covalent networks.
What are diamond and quartz composed of?
Diamond is composed of the element carbon, and quartz is composed of the elements silicon and oxygen.
How is melting point of silicon dioxide lower than melting point of diamond?
Smell
Is silicon dioxide a mineral?
No, silicon dioxide is a compound. There terms metal and nonmetal are used to describe elements.
Why silicon dioxide is a suitable for welding blankets?
because it has many strong covalent bonds in a lattice structure (such as diamond)
What are the differences between Silicon Dioxide and Diamond?
silicon dioxide is a compound and diamond is an element
Why is silicon dioxide a compound where as diamond is an element Explain?
Diamond consists of only one element (carbon). Whereas Silicon dioxide consists of two different elements (silicon and oxygen) that are chemically bonded in a fixed ratio. Hence Diamond is an element and Silicon dioxide is an compound.
How do you cut silicon carbide?
diamond
What is the symbol of diamond silicon and graphite?
Diamond and Graphite are allotropes of Carbon [chemical symbol: C]The chemical symbol of Silicon is Si.
Silicon dioxide diamond covalent network?
Not sure what that means... but both silicon dioxide (sand) and diamond are covalent networks.
What substance is an example of a network solid?
An example is the boron nitride. Another is silicon dioxide.
Is a diamond composed of oxygen and silicon?
The diamond is a crystallized, allotrope form of pure carbon.
Which has a stronger covalent bond carbon diamond or silicon?
Carbon (diamond) is much harder and stronger
Why is there an allotrope of silicon with the same structure as diamond but no allotrope of silicon with the same structure as graphite?
Because they have different properties.
What is the difference between quartz and diamond?
Quartz is silicon dioxide (sand). Diamond is an allotropic form of carbon.
What are diamond and quartz composed of?
Diamond is composed of the element carbon, and quartz is composed of the elements silicon and oxygen.
Why diamond has a higher melting point than silicon carbide?
The bond energy of Si -C is generally considered to be lower than that of the C-C, so a simple explanation is that diamond has a stronger bond. Both diamond and silicon carbide have a three dimensional network structure. Diamond consists of tetrahedral bonded carbon atoms whereas silicon carbide has many polymorphs (crystal structure which are temperature dependant). As you heat silicon carbide up the crystal structure changes. Silicon carbide does not melt "congruently" to give a liquid of the same composition, it decomposes at around 2700 0C .
