Francium would react with water by this equation:
2Fr + 2H2O -->2FrOH + H2 The products here are francium hydroxide and hydrogen gas.
However, it would be impossible to gather enough francium to demonstrate this reaction.
No, francium bombs have never been made. Francium is a highly radioactive and rare element that is not readily available in large enough quantities to create a bomb. Additionally, the extreme reactivity and short half-life of francium would make it challenging to use in a practical weapon.
An estimated value may be 0,3 microohm.meter.Yes
Yes, the Grand Canyon has been filled with water in the past. The Colorado River carved the canyon over millions of years, and at times in the past, the river has flooded and filled the canyon with water.
Francium has a metallic appearance (http://en.wikipedia.org/wiki/Francium). Due to its extremely short half life, no one has ever seen francium in large enough amounts to be visible. The largest amount of francium ever collected was 10,000 atoms of it. If one were to see a piece of francium however, it would probably appear as a brightly glowing object due to its high rate of decay.</P>
The element with atomic number 119 is a theoretical element and hasn't been observed. However, it does still have an IUPAC systematic placeholder name; which is Ununennium (Uue). Only one attempt has ever been made to make this element. That was in 1985, when Calcium-48 ions were bombarded at Einsteinium-254. It was a failure. If it were to be discovered, it would be the first element of period 8 and would probably fit in under Francium.

Francium is a highly radioactive and unstable element that is never found in its pure form in nature. If it were to be touched, it would likely react explosively with water or air. Due to its extreme rarity and radioactivity, no one has ever touched or felt francium.
Yes, have you ever been tested for a cat allergy?
by law they are to be killed at the end of the experiment
Yes, francium is highly reactive and will quickly react with water and oxygen in the air, producing heat and potentially catching fire. Due to its extreme rarity and short half-life, francium is not commonly encountered in everyday situations.
No animal should ever be tested on
If there ever was one on the lake it would be a water spout not a tornado. Tornadoes are on land not water. A water spout is on the water.

Nope. They keep the theory the way it is. No one changes it. Usually, when scientist have tested the theory and find out something new, they create a new theory instead of changing the first one.
Yes there tested at every conteset what ever it's size
No, the Mythbusters have not tested the existence of an invisible electrostatic wall.
Francium is considered the most active metal as it is at the bottom of Group 1 in the periodic table, making it the most reactive alkali metal. It is highly reactive, and its reactivity increases as you move down the group.
