What would a silicon based lifeform be like?

Due to the weak nature of silicon bonds, silicon-based life would be primitive and simple. The complex structures of the organic forms we see on earth would be lacking — instead we would see a blob or a clump of silicon compounds.

What life form uses silicon?

Scientists have long known that life on Earth is capable of chemically manipulating silicon. For instance, microscopic particles of silicon dioxide called phytoliths can be found in grasses and other plants, and photosynthetic algae known as diatoms incorporate silicon dioxide into their skeletons.

Are there any non carbon based lifeforms on Earth?

On Earth, all known living things have a carbon-based structure and system. Scientists have speculated about the pros and cons of using atoms other than carbon to form the molecular structures necessary for life, but no one has proposed a theory employing such atoms to form all the necessary structures.

Can silicon based life exist Quora?

Silicon is far more abundant on the Earth than carbon, but life here uses carbon, not silicon. Actually finding any life there, if it exists, will be extremely difficult for obvious reasons.

Is there silicon-based life on Earth?

So, the answer, at least for now, is no – although silicon can sometimes be used biologically as a sort of structural support (and there are some examples claiming silicon as an essential trace element) for carbon-based life – silicon-based life itself does not exist, as far as we know, because of the chemical and …

What are uses of silicon?

Silicon is one of the most useful elements to mankind. Most is used to make alloys including aluminium-silicon and ferro-silicon (iron-silicon). These are used to make dynamo and transformer plates, engine blocks, cylinder heads and machine tools and to deoxidise steel. Silicon is also used to make silicones.

Why are we carbon based and not silicon based?

So, a carbon–oxygen bond, being of similar strength to other carbon bonds, can easily swap out atoms, resulting in a chemical reaction. In the case of silicon, the silicon–oxygen bond—the first bond—is so strong that it’s very hard to break them apart. This is the reason why carbon is the basis of life and not silicon.

What is the chemical symbol of silicon?

Si

Does silicon-based life exist?

Why is silicon not the basis of life?

Silicon can grow into a number of lifelike structures, but its chemistry makes it unlikely that it could be the basis for alien life-forms. 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.

What are characteristics of silicon?

Characteristics: Silicon is a hard, relatively inert metalloid and in crystalline form is very brittle with a marked metallic luster. Silicon occurs mainly in nature as the oxide and as silicates. The solid form of silicon does not react with oxygen, water and most acids.

Why is life on Earth based on carbon instead of silicon?

It remains an open question why life on Earth is based on carbon when silicon is more prevalent in Earth’s crust. Previous research suggests that compared to carbon, silicon can form chemical bonds with fewer kinds of atoms, and it often forms less complex kinds of molecular structures with the atoms that it can interact with.

Is there life on silicon-based worlds?

Lei Chen and Yan Liang (BeautyOfScience.com) / Caltech Science fiction has long imagined alien worlds inhabited by silicon-based life, such as the rock-eating Horta from the original Star Trek series.

Could silicon be the basis for alien life forms?

Silicon can grow into a number of lifelike structures, but its chemistry makes it unlikely that it could be the basis for alien life-forms. Indeed, carbon and silicon share many characteristics. Each has a so-called valence of four–meaning that individual atoms make four bonds with other elements in forming chemical compounds.

What are the similarities between silicon and carbon?

Carbon and silicon are chemically very similar in that silicon atoms can also each form bonds with up to four other atoms simultaneously. Moreover, silicon is one of the most common elements in the universe.
