How many stable, pure substances(atoms and compounds not mixtures and heterogeneous substances) are there?

Question

Dr.A answered "Where?" so to clarify I mean how many stable pure substances are known to exist including synthetic ones.

Answer 1

The CAS registry system as classified over 32 million inorganic and organic compounds and over 59 million sequences.

This is probably a drop in the bucket compared to all possible compounds, especially considering the vast numbers that are extracted from various lifeforms each year. The number of pure synthetic compounds (man-made) is pale in comparison.

To put this into perspective, if you started reading the names of all of the known (not just existing) chemical compounds, you would never get done in your lifetime. More compounds are being added than the number you could read on a daily basis.

Answer 2

There are hundreds of thousands of compounds just in the human body, many of which have not yet been discovered. New ones are identified every month. And there are at least many hundreds of thousands if not millions of compounds from other sources. There is no known number. Incidentally, not all pure substances are stable.

Answer 3

Pure Substances Are

Answer 4

Zeta(K)* pi ^ sqrt ((3/4) * Delta (6.0233*10^23) ) * (2^e)
All matter and solids can be quantified in the paradoxical method; eliminating the instability factor via the statistical and fundamental entropy from any known and theoretically hypothesized combinations to the point of almost exact methodical estimation precluding the fact that there can be only one possible answer; which is one of a number of true values which is too large to quantify. Thank you for all of your time minus the speed of light multiplied by the logarithm of chance.

Answer 5

Some physicists think that the proton is inherently unstable, although with a very long half life.

Due to the fact that all atoms require protons and the physicists above claim the proton to be unstable then all matter as we know it is ultimately unstable.

So it depends what you define as stable and who you listen to?

Answer 6

Where?

I thing that it is impossible to know how many substances there are in the world
