Halogens are the name of a group of non-metal elements found on the Periodic Table, Group 7A (or 17). Halogens include fluorine, chlorine, bromine, iodine and astatine. Halogen lamps usually contain an inert (Noble) gas and a small amount of bromine or iodine surrounding the filament. It is a family of "Salt Producing" elements.
What else can I help you with?
Whaat is an extremely reactive family of elements?
halogenes
Electronegativity changes as you descended a group?
it decreases (check for instance the halogenes - F, Cl, Br, I, At)
In which family in the periodic table are the most reactive nonmetalsmily in the periodic table are the most reactive nonmetals?
halogenes/non metals
What kind of chemical bond is formed by transfer of electrons between alkali metals and halogenes?
An ionic bond is formed by electron transfer between alkali metals and halogens.
What family do chlorine and iodine belong to?
Together with bromine and fluorine they belong to the 'halogenes', group 7 in the periodic table.
What are found uncombined as monatomic species in nature?
Halogens are found in nature as a monatomic species ex. Hydrogen, Nitrogen, Oxygen, Flourine, Chlorine, Bromine, ect.
What are the most reactive nonmetals in the halogenes?
First of all, all halogens are non-metals. Secondly, the most reactive is fluorine, which reacts to nearly everything, hence it is rare. After fluorine comes chlorine, then bromine and iodine.
What are the following elements is an halogen?
bromine <><><><><> Halogens are group 17 elements, like fluorine, chlorine, bromine, iodine, astatine, and uus-117.
What are group 8A elements called?
I - Alkali Metals II - Earth Alkali Metals III - Boron Group IV - Carbon Group V - Nitrogen Group VI - Chalcogenes VII - Halogenes VIII - Noble Gases
How does the electron configuration affect the reactivity?
Valency determines the chemical properties of an atom by indicating how many unpaired valence electrons an atom has, allowing a chemist to determine how many and possibly what type of bonds the atom may form with other elements. For example, most elements with a "full valence shell" of 8 valence electrons (following the Octet Rule) will not react in solution because they cannot form bonds with other elements.
