Atoms within hydrogen halides are bound by covalent bonds, forming polar molecules.
One of the halogens, it may cause skin irritation.
A yellow-green toxic gas with a strong odour, one of the halogens.
The lightest halogen, a pale yellow-green, toxic gas, extremely reactive. Its best known compound is teflon.
A solid, grey substance which sublimates when heated. Its solution in alcohol is called tincture of iodine, it is a disinfectant.
Colourless, odourless gas, the monomer of teflon.
Used in the production of beryllium and as a catalyst.
A solid, grey substance which sublimates when heated. Its solution in alcohol is called ´tincture of iodine´, it is a disinfectant.
Addition is a reaction in which the molecules of two or more substances unite without the formation of a by-product.
A light yellow compound formed in the reaction of silver nitrate and potassium iodide.
Colourless, heavier-than-air gas with a pungent odour. It forms white fumes in moist air.
Hypochlorite ions are formed when water is disinfected with chlorine.
