What is the most stable moleucle?

Question

I know hydrogen is wrong because it is easily combustable, water being the product would be the next choice but I dont know that for sure

I was thinking nitrogen

In response to shofly12 and sarah those would not be molecules, but rather atoms

Answer 1

i would go with the noble gases. their molecules are very stable.

Answer 2

A molecule is a physical entity containing at least two atoms. By no stretch of this definition are the noble elements considered molecules. Indeed, their defining characteristic was their remarkable reluctance to form molecules.

As for the most stable molecule, thats an unanswerable question - it depends on the reaction conditions it is exposed to. You might consider water to be very stable - but drop a piece of sodium into water and you'll see a rapid and extremely vigourous reaction. For 'stability' as in low reactivity to a wide range of conditions, you could look to glass - that's why it's been used for centuries for making containers to keep things in. But even glass will react with hydrofluoric acid, which is used for etching glass. Of more modern materials, Teflon (PTFE, polytetrafluoroethylene) is pretty inert.

Answer 3

The Noble gasses with their Octet Rule are the most stable elements. I'd assume the further up you go the more stable they would be. So Helium would be very stable.

Although for molecule, Nitrogen gas (N2) is very good choice, there are better ones such as Van der Waal molecules like Ar2, (H2O)2, and Benzene-Ar, which are all very stable. Also, Carbon structures like Buckminster Fullerene or Carbon Nanotubes represnt amazing physical stability.

Answer 4

I have seen answers of others .

If you consider noble gas as a molecule( I would not because it contains only one atom), helium is the most stable.

For molecules difficult ot broke , nitrogen seems a good candidate under the form N2

an other form is fullerene C60, see my link

Answer 5

The noble gas atoms count as molecules.
The most stable, therefore, is helium, He.

Answer 6

i think its lead. as an atom. it takes the most energy to be divided or fused, and it is the last point at which molecules higher than it decompose to (ie: Uranium decomposes to lead)

molecule would probably be helium.

Answer 7

well elements are constantly trying to get to 8 valence elctrons or outer electrons. a stable element has 8. this element become hard to bond with because it will not give nor take any more electrons. an unstable element has few electrons. such as carbo.only 1 but this also makes it the most wanted to bond with. it is constantly trying to find elements to give its electron to so it may then have 8.

Answer 8

any noble gas, however, helium for example is one of them and a very stable one

Answer 9

i think it's the simplest one, the water molecule.

Answer 10

hydrogen
