Well I know why Carbon and silicon do not form simple ions. It is becasue if the were to form a ion they could either get 4 electrons or lose 4 electrons. Neither is easier so they just stay the same.
Si+CO2 ---------> SiC+SiO2
no but carbon does
When heated, they form Silicon carbide(SiC) a black and very hard compound.
Its most likely that Boron would react in a similar way as Aluminium because both of them are in the same group (IIIA) - one above the other.But actually, Boron behaves more like Silicon.Because: Boron is in very specific place in its period.This place is on the boundary between the metals (Li - Be) and nonmetals (C - Ne) which makes Boron a metalloid. Aluminium is in the next period, right under Boron (Their both are present in a common group).This place would give him more metal properties than Boron, so Aluminium turns out as one of the most common and widespread metals.Right next to Boron, Carbon is present.Carbon is in the nonmetal section of 2nd period, so its properties also would be different in contrast to these of Boron.But right under Carbon and right next to Aluminium, Silicon is present.Its nearer to the right side of the periodic table than Aluminium is, so its properties won't be namely metallic.But its also right under the typical nonmetal Carbon which would mean that its properties can't also be absolutely nonmetallic.This gives mixed properties to Silicon, making it a metalloid.Exactly like Boron. That's why Boron reacts more like Silicon.
With Carbon and Silicon both in the 4A column, there are too many ions to gain or lose. They instead share, to be more stable.
Boron (B)
Under favorable conditions, carbon and boron can react to form boron carbide.
they would form a covalent bond.
Si+CO2 ---------> SiC+SiO2
No. Silicon cannot form long chains or other complex molecules as carbon can because the Si-Si bonds are unstable. The silicon-hydrogen bonds are much weaker as well.
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.

Controversy about silicon's physical and chemical character dates to its discovery: silicon was first prepared and characterized in pure form in 1824, and given the name:Silicium (from Latin: silicis, flints),with an -ium word-ending to suggest a metal.However, its final name Silicon, suggested in 1831, reflects the more physically similar elements carbon and boron.

Silicon will react easily with oxygen (to form the network solid SiO2), hydrogen (to form silane gas), and the halogens to form silicon halides.

Silicon (Group 4) forms single covalent bonds with 4 Chlorine (Group 7) to become Silicon Tetrachloride (SiCl4). As well as the simple molecule silicon can form compounds containg Si chains such as Si3Cl8. silicon chlorides with chain lengths up to 6 are known. In this respect silicon is behving a little like carbon in forming chains.
