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.

Wiki User
∙ 12y agoNo it does not. It loses an electron to form a cation.

∙ 13y agoFr is in the 1st period of the Periodic Table... therefore it has 1 valence election. It is a cation so it would be Fr+
Wiki User
∙ 11y agoYes, it forms a positive ion (+1 charge). This is because it loses an electron.

What is the cost for 10g of francium?
Francium can form cations with the charge +1.
Is francium a cation or anion?
francium can form monovalent cations.
Would you expect francium to be found in its unreacted elemental form why?
Francium is very reactive and unable to remain in elementary form - excepting absorption on gold foils.
What is the formula for radioactive francium oxide?
Elements of Group I would have a charge of +1 when ionized. Since the OH ion has a charge of -1, the predicted hydroxide of francium would be FrOH.
Does Francium give away electrons easily or hold on to them tightly?
As an element of Alkali metals family, It will give away its electrons very easily to produce monovalent Fr+ ion
Does francium form an ion what is the charge and name of the ion. How do the subatomic particles -electrons- change when this element forms an ion?
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.
How many electrons are in a francium ion?
The ion Fr+ has 86 electrons.
What is the oxidation number of Fr?
It is in the first group. It shows only -1 number.
What is the ion formula of francium?
This compound was not prepared; the chemical formula will be FrF.
What is the electronegativity for francium?
The francium ion is positive (cation): Fr+1; L. Pauling electronegativity is 0,7.
What is the cost for 10g of francium?
Francium can form cations with the charge +1.
Is francium a cation or anion?
francium can form monovalent cations.
Which element is most likely to DONATE an electron to become an ion?
Francium (Fr)
Where can francium can be found on earth and in what form?
Francium exist in uranium and thorium ores; the chemical form is not known.
What element does francium bond with?
The chemistry of francium is not experimentally known; it is only estimated. Francium should be have properties similar to caesium.
Does francium gain or lose electrons and what state how many?
Francium lose one electron to form the cation Fr+.
Would you expect francium to be found in its unreacted elemental form why?
Francium is very reactive and unable to remain in elementary form - excepting absorption on gold foils.
