Argon is the 18th element of the periodic table so its atomic number is 18. On the contrary, composite numbers have more than two factors. Ferrocerium is a synthetic pyrophoric alloy that produces hot sparks that can reach temperatures of 3,000 C (5,430 F) when rapidly oxidized by the process of striking the rod, thereby fragmenting it and exposing those fragments to the oxygen in the air.
