Similarly to carbon and hydrogen, silicon and oxygen form numerous compounds. They are commonly known as silicates. Beach sand is a good example for a mixture of silicates.

Why methane and silicon dioxide have different melting points?
Methane, consists of discrete molecules with a formula CH4. Silicon dioxide, SiO2, is a covalent macro-molecule consisting of a lattice of covalently bonded Si and oxygen atoms (each silicon is attached to four oxygen atoms, each oxygen is attached to two silicon atoms. Solid methane is held together by intermolecular forces- London dispersion forces, which are weak., so relatively little thermal energy is required to break up the solid (-182 0C) Breaking the silicon dioxide lattice requires the breaking of strong covalent bonds- which requires much more energy- so it melts at a much higher temperature, 1600 0C
What element is most likely to form covalent bonds silicon oxygen chlorine or sulfur?
Among the elements listed, silicon is most likely to form covalent bonds. (Silicon is in the same periodic table column as carbon, which is the most likely of all atoms to form covalent bonds.)
Why is silicon dioxide a solid?
Silicon dioxide is not like carbon dioxide ( forms double bond with oxygen); this is expalined because it's energetically unfavourable for silicon dioxide to form double bond. 2p and 3p overlap b/w silicon and oxygen is not energetically favorable, so instead silicon binds covalent with 4 oxygen atoms( single bond) and forming a crystalline solid shape.
Why silicon dioxide is a suitable for welding blankets?
because it has many strong covalent bonds in a lattice structure (such as diamond)
What is silicon dioxide's molecular geometry?
The hybridization of Si in SiO2 is sp3.Si : [Ne]3s23p2SiO2 forms a covalent network in which the Si atoms form 4 single bonds to oxygen atoms. The oxygen atoms form 2 single bonds (and have two lone pairs) to Si atoms.Si is in the same group as C but because it contains the d orbitals (empty but there), Si is two large to form pi bonds.
Does silicon dioxide contain a covalent bond?
Silicon dioxide has covalent bonds.
What holds the atoms molecule together?
Bonds hold atoms together. There are hydrogen bonds, ionic bonds, and covalent bonds.
What is the number of covalent bonds that are possible for atoms of silicon?
In a sufficiently oxidizing environment, silicon can form up to six covalent bonds, as in SiF6.

Do covalent bonds hold together ions or atoms?
Covalent bonds hold atoms together. Ionic bonds hold ions together
What are atoms bonded together with covalent bonds?
When atoms are bonded together with covalent bonds, the result is a molecule.
What causes bonds to stay together?
Bonds stay together by electrons that travel on the atoms combined, holding the atoms together.
Are the bonds between silicon and chlorine in silicon tetrachloride single bonds?
No it is a covalent bond. Which is a bond where two atoms share a electron particles with one another.
How do atoms of a molecule stay together?
The atoms of a molecule stay together with chemical bonds.
How many electrons are shared in each bond of SiO2?
Silicon dioxide is a network giant molecule, the bonds are ALL single covalent bonds with two electrons. Each silicon is surrounded by four oxygen atoms at the corners of a tetrahedron, each oxygen atom is linked to two silicon atoms.Thereare no double bonds. Molecular SiO2 does not exist- heating SiO2 forms SiO not O=Si=O.
Do metallic bonds bond identical atoms together?
Metallic bonds bond identical atoms together if they are both metal atoms, but not if they are other identical atoms. For example, the bonds holding two chlorine atoms together to make Cl2 are not metallic bonds.
What bonds are atoms held together by?
covalent bonds.
