There are many types of vasculitis. Each type involves inflamed blood vessels. However, most types differ in whom they affect and the organs that are involved. The types of vasculitis often are grouped based on the size of the blood vessels they affect.
Chlorine is supplied as a gas, liquid and a solid. The gas is 100 percent elemental chlorine (Cl2), and is supplied in 150 lb. cylinders (10 inches in diameter and about 55 inches high) and in 2,000 lb. (ton) containers (30 inches in diameter and 82 inches high).
Cl2, a diatomic molecule, shares the pair of electrons and does not have an oxidation number. Cl2 is a free element so its oxidation number is 0. Most common diatomic molecular compound other than CO, are bonded with H like HCl, HF, HI so i would say +1 and -1 are their oxidation numbers in general. Dont be confused with diatomic element (Cl2, O2, N2) from diatomic molecular compound (CO, HCl, HF, HI) because diatomic element's oxidation number is equal to 0. Any element that is in an uncombined state such as Cl2 will always have an oxidation number of 0.
