in some water
this is a horrible idea, as francium is an element in the alkali metals, this family of elements reacts violently with water. for instance a small pellet of Potassium creates a bright flash and pops. as the elements move down in periods, they increase in reactivity, this would mean francium, would be the most reactive, a horrible idea would be to keep it in water. the best idea would be to store it in oil, as it will react with air.
You cannot get francium out of another material; it is impossible. Francium has a half-life of a few mere minutes, and this makes it so radioactive that it will just vaporize itself into a radioactively toxic gas that'll burn the skin off your face.
Francium is not an explosive material. Possible explosive reaction with water.
Francium is obtained by a nuclear reaction in a particle accelerator.
Francium is not explosive.
Francium was named after France, the country it was dicovered in.
Francium is very radioactive and very difficult to obtain; heating of francium due to the decay leads to instantaneous vaporization of francium.
no known odor for francium
Francium is not explosive.
Francium is a radioactive element.
Because the atom of francium is a whole row down from cesium. You see more YouTube videos of cesium in water because francium is highly radioactive, so it would be very hard to obtain a sample of francium to throw into water.
Francium should be a solid at standard temperature and pressure, as is cesium, the element next above it in its Periodic Table column. Note, however, that francium is so highly radioactive that it may be difficult to maintain any actual sample of it at standard temperature and pressure.
Francium is often ignored because it is the second rarest element on the planet. Only about 30 grams of it exist in Earth's crust at any given time. Nobody has been able to have more than a few thousand francium atoms in one place. Francium is also has a very short half-life, 22 minutes. Meaning that if you have a sample of francium half of it will have decayed into other elements after 22 minutes.
Francium was named after France, the country it was dicovered in.
Not known today but probably francium don't burn.
Francium has not applications and the oxide cannot be prepared.
Francium can form cations with the charge +1.
Francium is a metal.
Francium is a true chemical element, not an example.
Francium should be a solid at standard temperature and pressure, as is cesium, the element next above it in its periodic table column. Note, however, that francium is so highly radioactive that it may be difficult to maintain any actual sample of it at standard temperature and pressure.
Quite possibly francium (Fr, atomic number 87) is the most reactive element. Collecting a sample large enough to view is currently impossible, as it would vaporize due to the extreme heat of its decay. The longest isotopic half life of francium is 22 minutes.
We haven't sufficient francium for a measurement; also francium is autovaporized.
