Because silicon is a metalloid/semi-metal and carbon is a nonmetal, the bond is covalent.
One atom that can form a bond with silicon is oxygen, to form silicon dioxide, SiO2.
It makes a covalent bond. This means a bond between a metal and non-metal element.
Carbon is versatile because it can form single, double, and triple bonds. It can also form chains, branched chains, and rings. Also, carbon atoms bond fairly readily with other carbon atoms. It's much more energetically favorable for, say, a silicon atom to bond with an oxygen atom than another silicon atom; with carbon, the difference is less, so carbon-carbon bonds are more stable in the presense of oxygen than silicon-silicon bonds are... this is important, given that oxygen is the third most common element in the universe.
Silicon does not exhibit catenation property like carbon because of the larger size of silicon atoms compared to carbon atoms. This larger size results in weaker silicon-silicon bonds, making it less favorable for silicon to form long chains or rings like carbon does. Additionally, silicon's lower electronegativity compared to carbon leads to weaker bonding interactions, further reducing its tendency to exhibit catenation.
Carbon is in Group V. Thus, it needs 4 more electrons so as to achieve the octet structure in its valence shell. As such, carbon has make at most 4 single covalent bonds. The least number of covalent bonds carbon can make is 2 double bonds. We do not see an example of carbon forming 1 covalent bond involving the sharing of all 4 of its valence electrons.

One atom that can form a bond with silicon is oxygen, to form silicon dioxide, SiO2.
Silicon typically forms bonds with oxygen to create silicon dioxide, commonly known as quartz or silica. It can also bond with other elements like carbon, hydrogen, and various metals to form a wide range of silicon-based compounds.

A covalent bond
If you're looking for a replacement for carbon in the phrase "carbon-based lifeform" ... there really isn't one. Science fiction sometimes talks about silicon-based lifeforms, but they're not very likely for thermodynamics reasons (silicon would much, much rather bond with oxygen than with another silicon atom, and when that happens you get quartz, not complex molecules capable of supporting life).
C-C is a single-bond carbon C=C is a double-bond carbon... soooo.. if you need a triple-bond carbon make the hyphen thrice..
A covalent bond
silicon has 14 valence electrons, and therefore can form 14 covalent bonds. carbon is a main biological element (all living things are made of carbon-based compounds), silicon could be a candidate as a central biological element too because of the amount of electrons it has, would allow it to bond with many different elemements
Si has four valence electrons so silicon need to make four covalent bond.
Silicon is obtained by heating silica, or silicon dioxide with carbon or magnesium (or some reducing agent) in an electric furnace. And after that this mixture is coated on the object to make it water proof.
Tetrahedral, just like methane. The 'Si' (Silicon) is immediately below Carbon in Group 4. So it behaves very similarly to carbon . Silicon , like carbon has four outer most electrons in its outer energy shell , so it will make four bonds. One each to each of the Bromines (Br). Silicon like carbon has the ability to catenate, that is form chains by bonding to itself. This feature is not as strong in silicon. The crystalline structure of sand ( silicon dioxide) is such that silicon bonds to itself and to oxygen.
