Fr is in the 1st period. It removes an electron to get noble gas configuration. Fr+ does not have valence electrons.
Francium has 1 electron in its outermost energy level. It donates its outermost electron to stabilize its electron configuration. Francium(I) has no valence electrons.
Many energy levels of electrons and low effective nuclear charge/low Coulombic force.
Hydrogen (H) Lithium (Li) Sodium (Na) Potassium (K) Rubidium (Rb) Cesium (Cs) Francium (Fr)
Alkali metals such as Li, Na, K, Rb, Cs, and Fr each have 1 valence electron. This is because they have a single electron in their outermost electron shell, making them highly reactive and likely to lose that electron to achieve a stable electron configuration.
These six elements are Li, Na, K, Rb, Cs and Fr.
1
The ion Fr+ has 86 electrons.
Francium lose one electron to form the cation Fr+.
Many energy levels of electrons and low effective nuclear charge/low Coulombic force.
F for Fluorine.
When Fr is oxidised, it does so by donating electrons to the oxidant (eg. Oxygen, H+ )

The 2014 Scion FR-S has 16 valves.
The 2013 Scion FR-S has 16 valves.
word is that only 100 she devil FR's were made. you can still find the she devil on sites with out the FR but your best chance at finding a she devil FR is by checking ebay everyday.
Hydrogen (H) Lithium (Li) Sodium (Na) Potassium (K) Rubidium (Rb) Cesium (Cs) Francium (Fr)
Plus one (+), as Me+ where Me is Li, Na, K, Cs, Rb, Fr.
FATA consists of seven autonomous agencies: Kyber, Kurram, Orakzai, Mohmand, Bajaur, North and South Waziristan. It also includes 6 Frontier Regions - FR Bannu, FR Kohat, FR Tank, FR DI Khan, FR Lakki Marwat and FR Peshawar. (Division of areas by agency, teshil, subdivisions at the end of the document)
