Silicon has large and diffused p orbitals so it is unable to form Multiple bonds , so to satisfy the 4 valencies, it forms Si-chains. In CO2, on the other hand, the double bonds make CO2 a discreet molecule.
Elements like Silicon and Carbon show catenation.
Catenation
carbon has unique ability
catenation is the property of carbon that it can join with other carbon atoms to form carbon-carbon bonds. this can result in yhe formation of compounds with long change.
Catenation is a unique property of carbon to link with other carbon atoms to form rings or chains with the help of covalent bonds. Catenation is the reason for the presence of a large number of organic compounds in nature.
catenation is a unique property shown by carbon. for catination to occur, we need certain conditions to be satisfied. a most important factor is the size. carbon satisfies the size requirements which favours strong c-c bonds. but Si-Si bonds are not so strong in our conditions.
Silicon dioxide contains only silicon and oxygen - no carbon., The only carbon in a sample labelled " silicon dioxide", would be an impurity or contaminant probably on the surface
yes carbon is reactive because it has a property which other do not have calle catenation
Catenation is the linkage of atoms of the same element into longer chains. Catenation occurs most readily in carbon, which forms covalent bonds with other carbon atoms to form longer chains and structures. several other main group elements exhibit catenation, including silicon and sulfur.
this property is called as CATENATION.
Which one is mixture carbon dioxide = compound silicon = element silicon dioxide = compound or sand = mixture so sand is the answer.
Generally organic compounds have lots of carbons (tens of them in number). This is because of a property called catenation which allows carbon to form long chain of like atoms (other carbon atoms). Such property is usually not shown by other elements. Silicon show it to some extent. It has some compounds with upto 8 silicon chains.
