If i remember correctly H2O is also one of the first elements ever formed… most other elements come from stars
Discussion
…yes, this thread was a physics-heavy thread w/o the discussion of the biology that makes up the Universe.
H2O is not an element, it is a compound. ;-)
The first elements formed were Hydrogen, Helium, and Lithium as the early universe expended through temperatures and densities that were roughtly equivalent to the core of a star. The other elements had to wait a few million years for stars to form and start fusing Hydrogen into Helium, and then into Carbon and Oxygen in their cores. Then those stars had to explode as supernovae in order to spread those elements far and wide. Once those elements cooled gravity gradually drew them together and they formed clouds. And then molecules like water could form.
Ah yes, i meant hydrogen 😅 sry, not a physicist here
When I referred to H2O, it was in the context of water on Earth & if there is no water on a planet, there is no life form.
I did also refer to Hydrogen 1 as an element & H2O/water as a molecule - both accurate descriptions.
Nice explanation on the early formation of stars ⭐️
There is a reason why Hydrogen is the 1st element on the periodic table.
