At a temperature over 677 0C francium may be a gas.
Francium doesn't produce a gas.
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.
Francium is supposed to be a solid at room temperature.
The noble gas configuration of francium is [Rn]7s^1, where [Rn] represents the electron configuration of radon, a noble gas element. Francium has one valence electron in the 7s orbital, making it highly reactive.
The noble gas configuration for francium (Fr) is [Rn]7s1, where [Rn] represents the electron configuration of the noble gas radon. Francium has 87 electrons, with the last electron occupying the 7s orbital.
Francium is a highly reactive alkali metal that readily reacts with acids to produce francium salts and hydrogen gas. The reaction is very vigorous and can be explosive due to francium's extreme reactivity. Francium's scarcity and radioactivity make studying its reactions challenging.
When francium and oxygen react, francium oxide is formed. This compound is highly reactive and unstable due to francium's extreme reactivity. Francium is a highly radioactive element and is extremely rare in nature.
The chemical formula for francium mixed with water is Fr + H2O → FrOH + H2 (francium hydroxide and hydrogen gas are produced). Francium is a highly reactive alkali metal and would react violently with water to form francium hydroxide. However, francium is extremely rare and unstable, so this reaction has never been observed on a large scale.
The most stable oxidation state of francium is +1. Francium readily loses its single valence electron to attain a stable electron configuration similar to the noble gas configuration of cesium.
Francium is harmful because it is highly radioactive and can emit harmful radiation, which can damage cells and tissues in the body. In addition, francium can react violently with water, releasing hydrogen gas and potentially causing burns or injuries. Due to its extreme rarity and short half-life, francium is not a significant health concern in everyday life.
Mixing sulfuric acid with francium would result in a vigorous chemical reaction. Francium is a highly reactive alkali metal that would react violently with the sulfuric acid, potentially causing an explosion and generating hydrogen gas. This reaction would also produce francium sulfate and release a considerable amount of heat.
Francium reacts very vigorously with water, producing francium hydroxide and hydrogen gas. This reaction occurs because francium is an alkali metal and easily loses its outer electron when in contact with water, releasing energy in the form of heat and causing the explosion-like reaction.
