Francium doesn't produce a gas.
At a temperature over 677 0C francium may be a gas.
Francium is supposed to be a solid at room temperature.
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.
[Rn]7s1
This compound was not prepared but it should be FrCl.
Francium is a very rare metal that would oxidize very quickly. The word equation is francium + oxygen -> francium hydroxide + hydrogen gas.
Rubidium and Francium and pretty much the whole left side of the periodic table. That side swaps neutrons quite easily and therfore displace energy. Don't put Francium in Water. Rubidium in a bathtub has the same effect as a hand-grenade.
When francium is added to water, it reacts vigorously to produce francium hydroxide and hydrogen gas. Francium is a highly reactive alkali metal and is extremely rare and radioactive, making it difficult to study in large quantities.
it attains the configuration of neon or [He]2s22p6
Yes, decaying food can produce gas.
This reaction should be: 2 Fr + 2 H2O = 2 NaOH + H2
Francium was named after France, the country it was dicovered in.
