Can sulfur exist as a single atom?
Sulfur forms single bonds rather than double bonds as an element. It exists as disulfide but as an ion with two negative charges, not as an element. Sulfur (and Selenium also in the same group) due to its bigger atomic size has stronger Vander Waal forces among atoms. So it forms a solid structure at room temperature.

What is the word equation for carbon dioxide?
Example
| Step | Result | Equation balanced? |
|---|---|---|
| 1 | carbon monoxide + oxygen → carbon dioxide | |
| 2 | CO + O 2 → CO 2 | |
| 3 | Reactants: 1 × C, (1 × O) + (2 × O) = 3 × O. Products: 1 × C, 2 × O | Not balanced. |
| 4 | 2CO + O 2 → CO 2 |
What happens when Sulphur is burnt in oxygen?
Answer: Sulphur when burnt in air forms SO2. Sulphur reacts with oxygen as it burns in the presence of oxygen, producing Sulphur dioxide, which is acidic in nature.
How many atoms of oxygen is present in sulfur dioxide?

How was carbon named?
The word carbon probably derives from the Latin carbo, meaning variously “coal,” “charcoal,” “ember.” The term diamond, a corruption of the Greek word adamas, “the invincible,” aptly describes the permanence of this crystallized form of carbon, just as graphite, the name for the other crystal form of carbon, derived …
Is carbon a atom?
Carbon has an atomic number of six (meaning six protons, and six electrons as well in a neutral atom), so the first two electrons fill the inner shell and the remaining four are left in the second shell, which is the valence (outermost) shell.
How is carbon created?
Carbon and oxygen were not created in the Big Bang, but rather much later in stars. All of the carbon and oxygen in all living things are made in the nuclear fusion reactors that we call stars. When these stars die with a bang they spread the elements of life, carbon and oxygen, throughout the universe.
Where is carbon found?
Carbon is stored on our planet in the following major sinks (1) as organic molecules in living and dead organisms found in the biosphere; (2) as the gas carbon dioxide in the atmosphere; (3) as organic matter in soils; (4) in the lithosphere as fossil fuels and sedimentary rock deposits such as limestone, dolomite and …

Can life be non carbon based?
However, there are no known natural instances of life on Earth combining silicon and carbon together into molecules. Still, chemists have artificially synthesized molecules comprised of both silicon and carbon.
