These elements are not used as catalysts.
The halogen Group is a series of non metal elements.
The platinum group is often used for electrodes or catalyts because they do not combine easily with other elements.
These are the platinum metals.
A catalyst is anything which causes a chemical or physical reaction. As such almost anything other than the most inate chemicals could act as a catalyst.
most of the metals (either in the form of native metals or as their compounds) are known to act as catalysts for one reaction or the other.
Halogen elements are part of Group XVII. They have seven electrons in their outer shell. The halogen that is most associated with bleach is chlorine.

There are different elements that can be used to immobilize a reduced protein. Some of the common element include sulfur, halogen and nitrogen.
Iodine. If you mean the group of halogens, here's what Wikipedia writes about it: The halogens or halogen elements (/ˈhælədʒɨn/) are a group in the periodic table consisting of five chemically related elements, fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). The artificially created element 117 (ununseptium) may also be a halogen. In the modern IUPAC nomenclature, this group is known as group 17. The group of halogens is the only periodic table group that contains elements in all three familiar states of matter at standard temperature and pressure. All of the halogens form acids when bonded to hydrogen. Most halogens are typically produced from minerals of salts. The middle halogens, that is, chlorine, bromine and iodine, are often used as disinfectants. The halogens are also all toxic.

It is an element. It is a VERY poisonous gas. It is the most reactive of the halogen elements . Sometimes nicknamed the 'Tyrranosaurus Rex' of the elements. It is green/yellow in colour. It has the least atomic mass of the Halogen elements. It is used to make 'non-stick' pans, CFC's , and is often used in fire-retardants, or for fire-fighting.
iodine is used in girgnard's reaction bcz girgnard took this RX group and x indicates halogen group iodine is one of element of this group.
Halides are minerals that contain a halogen ion plus one or more other elements. Halogens are elements from Group 7A of the periodic table. This group includes the elements fluorine and chlorine.
