What is the f group in the periodic table?
What is the f group in the periodic table?
fluorine (F), most reactive chemical element and the lightest member of the halogen elements, or Group 17 (Group VIIa) of the periodic table. Its chemical activity can be attributed to its extreme ability to attract electrons (it is the most electronegative element) and to the small size of its atoms.
What group are F block elements?
The f-block appears as a footnote in a standard 18-column table but is located at the center-left of a 32-column full width table. While these elements are generally not considered part of any group, some authors consider them to be part of group 3.

Where IS f on the periodic table?
Fluorine
Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists at standard conditions as a highly toxic, pale yellow diatomic gas. As the most electronegative element, it is extremely reactive, as it reacts with all other elements, except for argon, neon, and helium.
How was fluorine found?
Fluorine was discovered in 1886 by French chemist Henri Moissan (1852-1907). Moissan collected the gas by passing an electric current through one of its compounds, hydrogen fluoride (H 2 F 2 ). Fluorine gas is used to make fluorides, compounds that were made part of toothpastes in the 1950s.
How do you identify the F block element?
The position of F Block Elements in the Periodic Table: F block elements are placed separately at the bottom of the periodic table. They are a subset of 6th and 7th periods.
How do you extract fluorine?
Fluorine is obtained by the electrolysis of a solution of potassium hydrogendifluoride in anhydrous hydrofluoric acid. Pure hydrofluoric acid is unsuitable for the process as it does not conduct electricity.
What is fluorine group?
Atomic number (Z) 9. Group. group 17 (halogens)
What compounds contain fluorine?
Some of The Popular Compounds Containing Fluorine Include
- Calcium Fluoride – CaF2.
- Xenon Difluoride- XeF2.
- Hydrogen Fluoride- HF.
- Uranium Hexafluoride (UF6)
- Sodium Monofluorophosphate (Na2PO3F)
- Sodium Fluoride (NaF)
- Stannous(II) fluoride (SnF2)
- Dichlorodifluoromethane (CF2Cl2)
What are f block elements called?
inner transition elements
The f block elements are the lanthanides and actinides and are called the inner transition elements because of their placement in the periodic table due to their electron configurations.
What are f block elements answer?
In the periodic table, they comprise the Lanthanide and Actinide sequences. Because of their location in the periodic table due to their electron positions, the f block elements are the lanthanides and actinides and are considered the inner transition elements. The electron shell’s f orbitals are packed with “n-2”.
