What element is located at Period 2, Group 15 ? 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’. Group 17 consists of fluorine, chlorine, bromine, iodine which form salts. Fluorine is used in drinking water and toothpaste as it reduces tooth decayIt is present in the clay used in ceramicsThey are present in chlorofluorocarbons that are used as refrigerantsThey are used to generate nuclear power For example, group 18 (or 8a) is the inert gases, which do barely interact chemically with other elements because they have no valence electrons. As it is in period 3 valence shell is 3 that is n=3 and since it's present in group 2, it has 2 valence electrons in the third shell. The other member of period 1, helium, is most commonly put with the other noble gases in group 18, as its exceptional inertia is exceedingly similar to that of the other noble light gases, neon and argon. Argon is most commonly used as an inert shielding gas. So, no. A. O B. This element is bromine (Br): group 17, period 7. Bromine is located in … "If all the elements are arranged in the order of their atomic weights, a periodic repetition of properties is obtained. Group 18 elements are known as noble gases.
