Group 17 of the periodic table of the elements (see Table 1.1) consists of the so called halogen elements fluorine, chlorine, bromine, iodine, astatine and the recently discovered element 117 (Organessian et al. in Phys Rev Lett 104:142502, 2010), although it is not yet known if this ...

Table 1 shows the ionic radii of halogen elements and it reveals that many halogen ions are able to be doped into TiO2 crystal to improve the optical property of TiO2 [32]. Further studies showed that halogen doping could not only narrow the band gap by being lowered to 1.4 eV [33] ...

They are found in group 17 of the Periodic Table, on the extreme right, close to the noble gases. Their valence electron configuration is the reason they are placed in group 17. Why are Group 7 elements called halogens? They are called halogens as they form salts with metals. The term...
Toxic chemicals and compounds surrounds us in everyday life and there is a growing desire to remove them wherever possible. What are halogen free cables, and how do they help? When we refer to halogens, we’re talking about a group of elements in the periodic table known to have harmful...

The halogens are the only periodic table group that contains elements in all three familiar states of matter at standard temperature and pressure. At room temperature and pressure, fluorine and chlorine are gases, bromine is a liquid, and iodine and astatine are solids. The halogens show ...
