(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.
The valence of francium is +1.
Francium has 87 electrons but the atom is neutral.
The compound francium permanganate has the chemical formula FrMnO4. Hope that helped!
Francium is an official name.
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 molecule is neutral.
Examples: francium-223 or Fr-223.
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.
This compound was not prepared; the chemical formula will be FrF.
The francium ion is positive (cation): Fr+1; L. Pauling electronegativity is 0,7.
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.
Francium is a highly radioactive and rare element, making it extremely expensive to produce. However, due to its extreme reactivity and short half-life, it is not commercially available for sale in bulk quantities like 10g.
