Why are there 118 elements instead of 92 elements?
Its just that we have found 118 elements. Higher elements are certenly possible only that they are highly unstable and radioactive. Higher elements can be created in labs,since they don't occur in nature, but they have a half life in order of microseconds. So, creating them is not economical.
