Why is fluorine in group 17?
Halogens are nonmetals in group 17 (or VII) of the periodic table. Down the group, atom size increases. As a diatomic molecule, fluorine has the weakest bond due to repulsion between electrons of the small atoms. Therefore, they are highly reactive and can gain an electron through reaction with other elements.
What group is fluorine in on the periodic table?
The Halogens
Group 7A (or VIIA) of the periodic table are the halogens: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
What is the charge of fluorine in group 17?
-1
As a general rule, fluorine is the most reactive halogen and astatine is the least reactive. All halogens form Group 1 salts with similar properties. In these compounds, halogens are present as halide anions with charge of -1 (e.g. Cl-, Br-, etc.).
What is the family name of 17th group element?

What is Group 16 on the periodic table called?
chalcogen
oxygen group element, also called chalcogen, any of the six chemical elements making up Group 16 (VIa) of the periodic classification—namely, oxygen (O), sulfur (S), selenium (Se), tellurium (Te), polonium (Po), and livermorium (Lv).
What is the special name given to the 17th group?
Group 17 elements are called halogens. The name halogens are from Greek halo (sea salt) and gens (producing, forming) and thus means ‘sea salt former’.
Which element is most active in group 17?
FLUORINE
The most active element in Group 17 is FLUORINE.
What are the elements in Group 17 of the periodic table?
Group 17 of the periodic table of the elements consists of the so-called halogen elements fluorine, chlorine, bromine, iodine, astatine with general electronic configuration ns2np5.
What is the atomic number of fluorine on the periodic table?
Fluorine – Periodic Table Element Fluorine Atomic Number 9 Symbol F Element Category Halogen Phase at STP Gas
What are the 17 elements of Group V I a?
Fluorine, Chlorine, Bromine, Iodine, Astatine, and Tennessine constitute group V I I A (17 group elements) of the long form of the periodic table. The elements of the group are known as halogens (halos = salt, gen = product). These are all p block elements with the differentiating electron entering the P -orbital.
Where are the halogens located on the periodic table?
The halogens are located on the left of the noble gases on the periodic table. These five toxic, non-metallic elements make up Group 17 and consist of: fluorine (F), chlorine (Cl), bromine (Br), …
