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.
Francium is a non meta element. Atomic number of it is 87.
co2 and o2
Mercury. Could kill someone easily. Uranium radioactive and can kill Francuim radioactive and can kill. And also blows up like a bomb.
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
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.
there are 2 different types of 'rare'. There is Super Rare and rare. Doris = Rare :)
a rare opportunity
its SUPER RARE!!!!!!
It is a rare species
She is ultra rare
He is definetly rare. As rare as he can be.
its a rare a super rare and a parallel rare
