This is a question our experts keep getting from time to time. Now, we have got the complete detailed explanation and answer for everyone, who is interested!
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 …
Could silicon-based life ever exist within the universe?
Could silicon-based life ever exist within the universe? Yes, although it is unlikely given the interaction between silicon and oxygen. … Yes, as silicon is in the same family as carbon and these elements have similar properties, although it is unlikely given the interaction between silicon and oxygen.
Can there be non carbon based life?
Non-carbon-based biochemistries. On Earth, all known living things have a carbon-based structure and system. … He considered that there was only a remote possibility that non-carbon life forms could exist with genetic information systems capable of self-replication and the ability to evolve and adapt.
Could we eat silicon-based life?
The number of basic types of foods that can give us energy are very limited, and all of them are carbon based, as carbon is needed in the Calvin and Krebs Cycles. Silicon-based lifeforms would most likely have no caloric value for human digestion.
What if humans were silicon-based?
Carbon readily bonds with oxygen, forming carbon dioxide (CO2), a small gaseous molecule that we humans exhale. Whereas silicon forms silicon dioxide (SiO2) with oxygen, which is a gigantic molecule commonly known as sand. Imagine, if we were silicon-based living organisms, we would probably be exhaling sand.

Is silicon a metal?
But unlike carbon, silicon a metalloid — in fact, it’s the most common metalloid on earth. “Metalloid” is a term applied to elements that are better conductors of electron flow — electricity — than nonmetals, but not as good as metals.
What percentage of a human is carbon?
The most important structural element, and the reason we are known as carbon-based life forms. About 12 per cent of your body’s atoms are carbon.
What elements can life be based on?
From the mightiest blue whale to the most miniscule paramecium, life as we know it takes dramatically different forms. Nonetheless, all organisms are built from the same six essential elemental ingredients: carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur (CHNOPS).
Is non organic life possible?
Prof Cronin said: “All life on earth is based on organic biology (i.e. carbon in the form of amino acids, nucleotides, and sugars, etc.) but the inorganic world is considered to be inanimate. … The research into creating ‘inorganic life’ is in its earliest stages, but Prof Cronin believes it is entirely feasible.
Is all life on earth carbon based?
Carbon is the backbone of every known biological molecule. Life on Earth is based on carbon, likely because each carbon atom can form bonds with up to four other atoms simultaneously.
What is the difference between carbon and silicon?
The key difference between silicon and carbon is that the carbon is a nonmetal whereas the silicon is a metalloid. Carbon and silicon, both are in the same group (group 14) of the periodic table. Hence, they have four electrons in the outer energy level.
Can life be nitrogen based?
Nitrogen is one of a handful of elements that have been suggested as alternatives to carbon as the basis of life elsewhere in the universe. Principally this is because it can form long chains at low temperatures with a liquid solvent such as ammonia (NH3) or hydrogen cyanide (HCN).
What is non organic life?
Worringer’s nonorganic or inorganic life posits an underlying inorganic force that is tethered to the processes and structures of organic life, he writes: “the morphological law of inorganic nature still echoes like a dim memory in our human organism” (Worringer, 1908 (1953), p. 247).
What are the 5 essential elements of life?
1. Note that most living matter consists primarily of the so-called bulk elements: oxygen, carbon, hydrogen, nitrogen, and sulfur-the building blocks of the compounds that constitute our organs and muscles. These five elements also constitute the bulk of our diet; tens of grams per day are required for humans.
What is the most essential element to life?
Carbon is the most important element to life. Without this element, life as we know it would not exist. As you will see, carbon is the central element in compounds necessary for life.
What are the 7 elements of life?
The seven Elements are Nature, Water, Fire , Earth , Light, Darkness, and Spirit.
Are humans made of stardust?
Stars that go supernova are responsible for creating many of the elements of the periodic table, including those that make up the human body. ‘It is totally 100% true: nearly all the elements in the human body were made in a star and many have come through several supernovas. …
Is there gold in the human body?
Average human body has 0.2 milligrams of Gold.
Human body has Gold! … An average person’s body weighing 70 kilograms would contain a total mass of 0.2 milligrams of gold. The trace amount of Gold if turned a solid cube of purified gold will make a cube of 0.22 millimeters in measurement.
What is the least abundant element in our body?
Magnesium is the least common of the essential elements in the human body. Some 300 or so enzymes require magnesium ions to function properly, and magnesium ions interact with compounds such as DNA, RNA, and ATP.
Is silicon harmful to humans?
Silicon is non-toxic as the element and in all its natural forms, nameli silica and silicates, which are the most abundant. … Silicon may cause chronic respiratory effects. Crystalline silica (silicon dioxide) is a potent respiratory hazard.
What does silicone do to steel?
Mechanical adhesion occurs when one substance — in this case, silicone rubber adhesive — fills tiny voids in a second substance, such as metal. The friction of the adhesive against the edges of the small imperfections in the solid surface acts as a bond holding the two materials together.
What are 3 uses of silicon?
- The element is a major constituent in ceramics and bricks.
- Being a semiconductor, the element is put into use for making transistors.
- Silicon is widely used in computer chips and solar cells.
- It is a vital component of Portland cement.
- Silicon is used in the production of fire bricks.
Why is carbon better than silicon for life?
Generally, carbon bonds are twice as strong as silicon bonds. … Furthermore, carbon bonds are also unaffected by water, giving carbon another advantage in the most likely liquid medium for life. Silicon, on the other hand, doesn’t bond as well to other silicon atoms, and not well at all in the presence of many liquids.
Is Arsenic bad for carbon based life?
Late in 2010, scientists participating in a NASA news conference dropped a bombshell: they had found evidence that bacteria in California’s Mono Lake were metabolizing arsenic and using it in their life processes. This was huge news, since arsenic is toxic for carbon based life.
Which element is most like oxygen?
Oxygen is in group 16/VIA, which is called the chalcogens, and members of the same group have similar properties. Sulfur and selenium are the next two elements in the group, and they react with hydrogen gas (H2) in a manner similar to oxygen.
