Group 17 elements are a diverse group of metalloids characterized by the presence of 7 valence electrons arranged in a square planar structure. These elements exhibit characteristic properties and chemical behaviors due to their electron configurations.
The members of Group 17, also known as halogens, have an atomic number of 7. This simple configuration results in a valency electron configuration of [Ne]3s^23p^4. The atoms of this group have a relatively high electronegativity, meaning they can readily accept electrons, leading to the formation of ionic bonds.
The elements in Group 17, with the exception of francium, are highly reactive. They are capable of losing their valence electrons to attain a stable configuration, resulting in a wide range of chemical behaviors. These elements are often used in various industrial and laboratory applications, including the production of salts, pharmaceuticals, and plastics.
Examples of elements in Group 17 are:
Chlorine (Cl)
Bromine (Br)
Iodine (I)
Astatine (At)
These elements are highly reactive and should be handled with caution. They should not be directly exposed to air or moisture to prevent oxidation
