Because the conditions for it to emerge were favourable on pre-biotic Earth. The exact conditions required and the process by which life emerged are the domain of the field of research called abiogenesis.
Yes, The elements hydrogen, nitrogen, oxygen, and sulfur are all molecular elements that exist in nature. Due to their reactivity, it is rare to find the halogens and phosphorus in their elemental forms in nature.
Sodium is very reactive and this is the cause for which there doesn't exist uncombined in nature.
The atomic weight (not mass) of chlorine is now [35,446; 35,457]. I don't understand "no chlorine with mass exist in nature".
Francium is an example of an alkali metal that does not exist independently in nature or in the laboratory due to its extreme rarity and high radioactivity. It has a very short half-life and decays quickly into other elements, making it difficult to isolate and study.
Neon tetrafluoride, but that compound doesn't exist in nature, you basically have to force it.
No, blue trees do not exist in nature.
forces exist in nature
No, there are no bugs with red blood that exist in nature.
All alkali metals exist in nature as compounds.
Arsenic is actually very common in nature.
Yes, The elements hydrogen, nitrogen, oxygen, and sulfur are all molecular elements that exist in nature. Due to their reactivity, it is rare to find the halogens and phosphorus in their elemental forms in nature.
they do
Sausage roll
Yes, it does.
Americium is an artificial chemical element and don't exist in the nature.
It is dependent on the definition of the nature. If Nature here means vegetations, plantation, animal and bird life and like such things, then yes. Nature can exist. Nature is explored by the men of current era. The nature was there in old times too but unexplored. If the nature means here a Creator and Sustainer the too, yes. Because the man is dependent not the nature.
Because they do not exist naturally in nature.
