symbol for halide is RX
where R can be any element and X can be any element from halogen group like
HCl,HBr where H is R and {Cl,Br} is X
halogens and noble
The two most reactive groups of elements in the periodic table are the alkali metals and the halogens. Halogens are nonmetals located in group 17 of the periodic table and include elements like fluorine, chlorine, and iodine.
There are lots of examples unused single letters and pairs of letters- two most commonly used by chemists when they wan't to discuss generic properties, are X (often used to represent the halogens), M (used for metals)
The family that combines with metals to form salts is the halogen family. There are other nonmetals that can be mixed with metals to form salts, but halogens are the most common.
Halogens!! :D its the most reactive nonmetal and has 7 valence electrons!
The symbol for halogens on the periodic table is "X", with specific elements like fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At) representing this group.
Bromine is an element, one of the halogens. Its chemical symbol is Br.
halogens and noble
I do not know so don't ask this question again

Halogens Apex ;)
We find five halogens in periodic table. Those are non metal elements. Fluorine and chlorine gases are examples.
Bromine is in Group 7: The Halogens, below Fluorine and Chlorine but above Iodine and Astatine.

Halogens are in Group 7
any alkaline earth metals
