Francium atom. (periodic trends)
The chemical formula (not equation) of a theoretically possible francium phosphide is Fr3P.
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.
This compound was not prepared; the chemical formula will be FrF.
It is in the first group. It shows only -1 number.
The electron configuration of Fr, or Francium starts with the base configuration of [Rn]. The outer shell is 7s1, giving 1 valence electron.
Fr (Francium) has a larger atomic radius than F (Fluorine) because atomic radius increases as you move down a group in the periodic table. Francium is located at the bottom of the alkali metal group while Fluorine is at the top of the halogen group.
The chemical formula (not equation) of a theoretically possible francium phosphide is Fr3P.
Francium
The chemical symbol of francium is Fr.
Francium is a highly radioactive alkali metal element with the atomic number 87 and symbol Fr. It is the second rarest naturally occurring element in the Earth's crust and is extremely unstable, making it difficult to study. Francium was discovered in 1939 by Marguerite Perey.
The chemical symbol of francium is Fr correct !
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.
Fr = Francium - the chemical element of atomic number 87, a radioactive member of the alkali metal group. Francium occurs naturally as a decay product in uranium and thorium ores.
Francium has only the cation Fr+.
