Francium is a very rare substance witch has trace amounts of itin the world not enuth is known at this moment in time because we need the technology to find it. It is the second rareist element found in nature. only a few granes of francuim are found every year like this and to find more and make it in sciences labs trew genetic moderationof that element i hope this has helped you Tom Dobbie age 14
