Elements are the same size regardless of how they are synthesized. It is true, however, that small stars create fewer elements, and that the elements they create are lighter. A normal G-type star can, during the course of its evolution along the Main Sequence, produce elements up to iron. For elements heavier than that, larger stars are required; when they go nova, they can produce elements as heavy as uranium and beyond.
Chemical elements are combined to produce chemical compounds.
The Sun can only produce elements up to carbon and oxygen through nuclear fusion in its core. For elements heavier than carbon and oxygen, higher temperatures and pressures are required, which can only be achieved in more massive stars or during supernova explosions.
Natural gas was first discovered in ancient times by the Chinese, who used it to evaporate seawater to produce salt. However, the first recorded discovery of natural gas in the modern era was in the 17th century in Fredonia, New York, USA.
