Where is neon found in earth? south america? north america?

Neon is usually found in the form of a gas with molecules consisting of a single Neon atom. Neon is a rare gas that is found in the Earth's atmosphere at 1 part in 65,000. I'm not 100% sure but i am pretty sure it is found in both places but more is in South America. Just incase, wait for someone else to answer.
