Francium is rare because if its incredibly short half-life. The longest-lived isotope of francium has a half-life of 22 minutes. This means that if you have a given mass of francium, half of it will have decayed into something else after a 22 minute period. Francium is itself a product of Radioactive decay, however it decays so quickly after forming that there is never a large amount of it.

When was francuim discovered?

French scientist Margeurite Perey discovered francium (Fr, atomic #87) in 1939, naming it after her home country. Francium is extremely rare and is a radioactive decay by-product. Only 20-30 grams (about 1 ounce) exist naturally in the earth's crust at any given moment. Many of its physical properties are unknown because of its extremely small quantities and the fact that its three primary isotopes decay in a matter of minutes.
