Francium has only the cation Fr+.
Phosphorus typically forms three negative ions.
Francium ions typically have a +1 charge. Francium is an alkali metal in group 1 of the periodic table, and like other alkali metals, it tends to lose one electron to achieve a stable outer electron configuration.

The compound FrOH is known as francium hydroxide. It consists of francium (Fr), an alkali metal, and hydroxide (OH) ions. Due to the extreme radioactivity and rarity of francium, francium hydroxide is not commonly encountered or studied in detail.
Negative ions supposedly kill some bacteria. There is some debate on how effective this is and how many negative ions you have to have circulating to kill bacteria.
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 compound formed between sodium and francium would be NaFr, with sodium as the cation and francium as the anion. This compound would have a 1:1 ratio of sodium to francium ions.
Francium has 87 electrons.
Negative ions go to a positive electrode.
Negative ions are formed when atoms accept electrons.
Francium has 87 electrons.
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.
