Why does silicon show more Covalency than carbon?

Silicon show higher covalency than carbon because the silicon have d-orbitals due to which it can show the covalency of up to 6 but the d-orbitals are absent in carbon atoms due to which it cannot show covalency of more than 4.

Why does carbon Show Covalency of 4?

In carbon, due to absence of d-orbital, only s and p-orbitals are available for bonding, therefore, it can accommodate only four pairs of electrons around it. Thus, it has a maximum covalency of four.

What is the relation between carbon C and silicon Si )?

Since carbon is more electronegative than hydrogen the C-H bond is polarized towards carbon resulting in a more protic hydrogen (Figurea). In contrast, the lower electronegativity of silicon results in a more hydridic hydrogen (Figureb)….Electronegativity.

What is Covalency of silicon?

Maximum covalency of carbon is 4, whereas maximum covalency of silicon is 6.

What is the maximum valency of silicon?

Valency of First 30 Elements

Why carbon has more density than silicon?

The catenation bonds of silicon are very weak. C-C bond is much stronger than Si-Si bond ; thus silicon bonds break easily. Hence compounds of Carbon are much more stable than Silicon.

Why is maximum Covalency of silicon 6?

Note : It is important to note that although carbon and silicon belong from the same group but the maximum covalency shown by carbon atom is four whereas the maximum covalency shown by silicon atom is six because of presence of vacant d-orbitals in silicon, it can share all its valence electrons to form covalent bond.

How is Covalency of Si 6?

Maximum covalency of carbon is 4, whereas maximum covalency of silicon is 6. 2.

What is the maximum covalency of silicon 6?

Correct Option: A Carbon and Silicon both is belongs to IVth group and carbon have maximum valency of 4. But Si have vacant d-orbitals and can be used to accomodate more electrons. Thus, the maximum cavalency of Si can be 6.

Why is density of silicon less than carbon?
