The discovery took place at the Curie Institute in Paris. The element takes its name from the country it was discovered in-France.]]> 2017-10-23 16:23:08 UTC https://padlet.com/samuel_clark/rl4mdkpd9f9c/wish/199661932 samuel_clark https://padlet.com/samuel_clark/rl4mdkpd9f9c/wish/199665680 2017-10-23 16:29:49 UTC https://padlet.com/samuel_clark/rl4mdkpd9f9c/wish/199665680 samuel_clark https://padlet.com/samuel_clark/rl4mdkpd9f9c/wish/199670718 Francium is found in uranium minerals, this means it is slightly radioactive. Even though it is in less than 1% of the earth's crust in can still be man made by battering thorium with protons.
