The density of an element is determined by its Atomic Mass and atomic structure. Silicon has a larger atomic mass compared to carbon, but its atomic structure is less compact, leading to a lower density. Silicon atoms are larger and have more space between them, resulting in a lower mass per unit volume compared to carbon. This difference in atomic structure and arrangement contributes to the lower density of silicon compared to carbon.

Is carbon a more stable element than silicon?

Yes, carbon is a more stable element than silicon. Carbon forms stronger bonds due to its smaller atomic size, leading to greater stability in its compounds. Silicon, on the other hand, tends to form weaker bonds and is less stable compared to carbon.


What element is less electronegative than silicon?

Aluminum is less electronegative than silicon.


The mantle has less aluminum and less what than the crust does?

The mantle has less aluminum and less silicon than the crust does.


Why silicon does not show catenation?

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.


Which has a stronger covalent bond carbon diamond or silicon?

Carbon diamond has stronger covalent bonds than silicon because carbon-carbon bonds are shorter and stronger than silicon-silicon bonds due to the smaller size of carbon atoms compared to silicon atoms. This results in a more tightly bonded crystal lattice structure in diamond compared to silicon.


What non metal has 4 valence electronsproperties similar to carbon and an atomic mass slightly less than phosphorus?

The non-metal that fits this description is silicon. Silicon is located below carbon in the periodic table, has 4 valence electrons, and its atomic mass is slightly less than phosphorus. Like carbon, silicon can form covalent bonds and exhibits similar properties in terms of bonding and structure.


Which has a higher density iron or silicon?

Iron is more dense than silicon.


Why is carbon more electronegativea than silicon?

Carbon is more electronegative than silicon because carbon has a smaller atomic size and higher effective nuclear charge compared to silicon. This results in a stronger attraction for electrons in the carbon atom, making it more electronegative. Additionally, carbon's electron configuration allows it to achieve a stable octet more readily than silicon, further enhancing its electronegativity.


Will silicon sink or float in water?

Silicon will sink in water because it has a higher density than water.


What is it about silicon that makes it a possible carbon substitute in a system?

Theoretically yes, but it is quite implausible. Silicon forms less stable structures than carbon and silicon compounds would be solid at standard conditions and would, therefore, be quite hard to use by organisms.


Does silicon float or sink in water?

Silicon sinks in water because its density is higher than that of water.


Why FET produces less noise than BJT?

because the fet is made out of carbon metal oxide and the bjt is made out of silicon or germanium
