1. Naturally: francium 221 and francium 223 appear in the decay chains of neptunium or uranium 235.
2. Artificially: francium isotopes can be obtained by nuclear reactions in laboratories.
Francium and fluoride can form an ionic compound called francium fluoride. Francium is a highly reactive alkali metal, while fluoride is a negatively charged ion. When combined, francium will donate its electron to fluoride, forming a stable compound with a 1:1 ratio of francium to fluoride ions.
The products of francium fluoride would be francium cations (Fr+) and fluoride anions (F-) due to the reaction between francium (Fr) and fluoride (F) ions. Francium is a highly reactive alkali metal and fluoride is a halide ion, so they would combine to form a stable ionic compound.
The formula for francium periodate is FrIO4. Francium is a highly reactive alkali metal, while periodate is an ion composed of iodine and oxygen.
Francium is a cation because it loses an electron to become positively charged.
Hydrogen and francium can combine to form a compound with the formula HFr, which stands for hydrogen francium. This compound would be highly unstable and reactive due to the extremely high reactivity of francium. Francium is a rare and radioactive element that is highly unstable and difficult to handle, making it unlikely to form stable compounds with hydrogen.
As an alkali metal francium form the cation Fr+. A specific name doesn't exist. Transformation in a cation involve the loss of an electron.
Francium has the lowest electron affinity among all the elements because it is highly reactive and readily loses an electron to form a positive ion. This means that francium has a very low tendency to gain an electron.
Francium and fluoride can form an ionic compound called francium fluoride. Francium is a highly reactive alkali metal, while fluoride is a negatively charged ion. When combined, francium will donate its electron to fluoride, forming a stable compound with a 1:1 ratio of francium to fluoride ions.
The ion Fr+ has 86 electrons.
It is in the first group. It shows only -1 number.
This compound was not prepared; the chemical formula will be FrF.
Francium has the lowest ionization energy. Think of it this way, France - Francium. France has never won a war and is considered to be weak. Francium is weak!
Fr+1 or Fr+, because Francium is an alkali metal (like Na or K) and forms 1+ charged ions by reduction of other substances (very reactive, explosive reaction, even with water!).
The products of francium fluoride would be francium cations (Fr+) and fluoride anions (F-) due to the reaction between francium (Fr) and fluoride (F) ions. Francium is a highly reactive alkali metal and fluoride is a halide ion, so they would combine to form a stable ionic compound.
The formula for francium periodate is FrIO4. Francium is a highly reactive alkali metal, while periodate is an ion composed of iodine and oxygen.
The compound francium permanganate has the chemical formula FrMnO4. Hope that helped!
Francium exist in uranium and thorium ores; the chemical form is not known.
