The atomic mass of the most stable and common isotope of francium, 223Fr, is 223,019 735 9(26).
(A)Fluorine due to its high effective nuclear charge (B)Fluorine due to its low effective nuclear charge(C) Francium due to its great amount of shielding (D)Francium due to its low amount of shielding .(answer choices)
Not known today but probably francium don't burn.
Francium has not applications and the oxide cannot be prepared.
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.
The valence of francium is +1.
The cation of francium is Fr+.
Francium can form cations with the charge +1.
Francium has 87 electrons but the atom is neutral.
Francium is an official name.
Francium has no uses. There are currently no uses for francium outside of basic scientific research.
The molecule is neutral.
Examples: francium-223 or Fr-223.
It is Hydrogen.
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.
Francium, Fr, atom number 87, is an element, so it is uncharged metal atoms. It doesn't normally occur in nature, both isotopes are unstable and artificially made.It can easily donate one electron, becoming Fr+ion: charge +1, because it is an alkali-group(I) element like sodium.
The atomic mass of the most stable and common isotope of francium, 223Fr, is 223,019 735 9(26).
