What family or group is fluorine?
The Halogens
Group 7A (or VIIA) of the periodic table are the halogens: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). The name “halogen” means “salt former”, derived from the Greek words halo- (“salt”) and -gen (“formation”).
Is fluorine a family name?
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….
| Fluorine | |

| Atomic number (Z) | 9 |
| Group | group 17 (halogens) |
| Period | period 2 |
| Block | p-block |
Is fluorine acidic or basic?
Because fluoride is the least stable (most basic) of the halide conjugate bases, HF is the least acidic of the haloacids, only slightly stronger than acetic acid. HI, with a pKa of about -9, is one the strongest acids known.
What is fluorine formula?
Fluorine is the chemical element in the periodic table that has the symbol F and atomic number 9. In its pure form, it is a poisonous, pale, yellow-green gas, with chemical formula F2. Like other halogens, molecular fluorine is highly dangerous; it causes severe chemical burns on contact with skin.
What is the Lewis dot structure of fluorine?
Fluorine requires only one valence electron in order to complete its octet. Therefore, two atoms of fluorine form covalent bond with each other. In the representation of the electron dot structure of ${{\rm{F}}_{\rm{2}}}$, the valence electrons are represented by dots around each fluorine atom.
Where is fluorine used?
What are the uses of fluorine? Fluorine is critical for the production of nuclear material for nuclear power plants and for the insulation of electric towers. Hydrogen fluoride, a compound of fluorine, is used to etch glass. Fluorine, like Teflon, is used to make plastics and is also important in dental health.
What is the most common form of fluorine?
The most common fluorine minerals are fluorite, fluorspar and cryolite, but it is also rather widely distributed in other minerals. It is the 13th most common element in the Earth’s crust. Fluorine is made by the electrolysis of a solution of potassium hydrogendifluoride (KHF2) in anhydrous hydrofluoric acid.
What is fluorine classified as?
Fluorine is a light element classified as a halogen that is the most electronegative element known and is, therefore, highly prone to binding with metallic elements in nature to form salts.
What are the five uses of fluorine?
and flat panel display production.
What is the group for fluorine?
Fluorine (F), most reactive chemical element and the lightest member of the halogen elements, or Group 17 (Group VIIa) of the periodic table.
What family does fluorine belong to?
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.
