Both carbon and silicon commonly form compounds, easily sharing electrons with other elements. Carbon and silicon are often combined, with carbon serving as silicon’s backbone. However, silicon can also form silicon polymers, which are silicon and oxygen structures.
Why silicones are considered valuable?
Valued for their electrical-insulating properties, chemical stability, and the wide temperature range over which they retain resiliency, silicone rubbers are used mainly in O-rings, heat-resistant seals, caulks, gaskets, electrical insulators, flexible molds, and (owing to their chemical inertness) surgical implants.
Why is silicon life not possible?
The fact that silicon oxidizes to a solid is one basic reason as to why it cannot support life. Silica, or sand is a solid because silicon likes oxygen all too well, and the silicon dioxide forms a lattice in which one silicon atom is surrounded by four oxygen atoms.
Who invented silicon?
Jöns Jacob Berzelius
Silicon was discovered by Jöns Jacob Berzelius, a Swedish chemist, in 1824 by heating chips of potassium in a silica container and then carefully washing away the residual by-products. Silicon is the seventh most abundant element in the universe and the second most abundant element in the earth’s crust.
Why is silicon more reactive than carbon?
The bond energy for a C-C bond is slightly greater than for a C-O bond, while the Si-O bond is significantly stronger than the Si-Si bond. This difference is reflected in the chemistry of silicon versus carbon compounds.
Why is pure silicon so expensive?
Essentially silicone costs more due to the high energy costs associated with its manufacture (conversion of sand to high purity silica, then further refinement of silica before the chemical reactions that polymerise it), there are also a number of expensive components needed during the manufacture of silicone (copper …
Who invented silicone?
Franklin Hyde, a chemist who decades ago turned a useless sticky goo into a common family of industrial raw materials called silicones and who also invented a process for making an almost-pure glass used today in fiber optic technology, died Monday at his home on Marco Island, Fla. He was 96.

Why are there so many hydrocarbon compounds in the world?
Because carbon forms strong bonds to both itself and to hydrogen, and since carbon can form four bonds you have a lot of possible connectivities. 25 insanely cool gadgets selling out quickly in 2021. We’ve put together a list of incredible gadgets that you didn’t know you needed! Originally Answered: Why there many hydrocarbon compounds?
Are there any hydrocarbons with more than one double bond?
There are other straight-chain hydrocarbons that are unsaturated containing more than one multiple bond, some with more than one double bond, and some with a mixture of double bonds and triple bonds. The combinations and permutations are endless, but there are only a few of the highly unstable materials.
How are the different types of hydrocarbons different?
We can distinguish several types of hydrocarbons by differences in the bonding between carbon atoms. This leads to differences in geometries and in the hybridization of the carbon orbitals. Alkanes, or saturated hydrocarbons, contain only single covalent bonds between carbon atoms.
What is the physical description of silane gas?
Physical Description. Silane is a colorless, flammable and poisonous gas, with a strong repulsive odor. It is easily ignited in air, reacts with oxidizing agents, is very toxic by inhalation, and is a strong irritant to skin, eyes and mucous membranes. Silane is lighter than air. Under prolonged exposure to fire or heat…
