What are the things that have francium in it?

Answer 1

This might be a disappointing answer, but Francium is so rare that it isn't usually sold. So if you're looking for something about the price of Francium for a school project, you can just write about Francium's rareness. Your teacher would understand, don't worry! Personally, I think that even if Francium was out for selling, it would cost a lot of money. Just trust me! If you don't believe it, then look around the internet. You may not be able to get the answer.

Answer 2

Francium is a natural radioactive chemical element, atomic number 87, an alkali metal. Francium is placed in group1 and period 7 of the Periodic Table of Mendeleev.

Francium was discovered by Marguerite Perey in 1939 during a study on actinium-227: she observed an energy level possibly attributable to a new element. After some chemical experiments she was sure that the radiation is from a new chemical element, after this called francium. Francium hasn't practical applications; it is only a subject of scientific research.

Estimated properties of francium - Melting point: 27 0C - Boiling point: 677 0C - Density: 1,87 g/cm3 - Heat of fusion: 2 kJ/mol - Heat of vaporization: 65 kJ/mol - Ionization energy: 380 kJ/mol - Atomic covalent radius: 260pm - Thermal conductivity: 15 W/m.K - Electrical resitivity: 3 microohm.m - Crystalline structure: body centered cubic - Paramagnetic---------------------------------------------------Electron configuration: [Rn]7s1Pauling electronegativity: 0,7Valence: +1

Answer 5

Francium is an alkali metal placed in group 1 and period 7 of the Mendeleev table. Francium is radioactive and extremely scarce; francium has the highest electronegativity in Pauling system. The valence of francium is +1. Being so rare and unstable the chemistry of francium is only superficially known.

Answer 6

Its a very very rare alkali metal, only one ounce is every in the earths crust at any one time.

Answer 7

you get it as a by product of uranium there is thought to be only 30g of it in the earths crust

Answer 8

Francium is not a commercial product; it is used only in research laboratories;

all the francium in the world is cca. 30 g.

Answer 9

Francium hasn't practical uses.
