As they are toxic they can kill organisms. Only a small amount is needed to kill microorganisms. This small amount does not affect us humans. They can be used to purify drinking water and swimming pools. Chlorine can also be used as a bleach.

Atomic number of halogen?
For all practical purposes, there are 4 halogens, and they all have different atomic numbers because they're different elements. They are: fluorine, #9, chlorine, #17, bromine, #35, and iodine, #53. Astatine is in this group as well but you're not likely to ever have to deal with it. The halogens (minus astatine) are very common in chemistry, and it's important to know how they work. When they form ions, their charge is always -1 because they gain 1 electron. The 4 listed above are also diatomic, held together as a pair by a single, non-polar covalent bond. Dispersion forces cause fluorine and chlorine to exist as gases, bromine as a liquid, and iodine as a solid. They react readily with metals to form crystalline solids. Bonded with hydrogen, they form binary acids. They can also replace hydrogen in hydrocarbons to create fluoro-chloro-bromo-carbaons, which are harmful to the environment.
What ways can you use iodine?
iodine solution is used for finding starch in substances iodine solution is used for finding starch in substances
What is fluorine mass number?
Fluorine is a non metal element. Atomic mass of it is 19.
What are some interesting facts about iodine?
iodine is a solid halogen that can sublimate into a violet colored gas. it is also very useful in health. The name originates from the Greek word Iodes meaning "violet". When dissolved in alcohol, it is a powerful antiseptic germicide.
What is halogen used for?
Halogens are used in light bulbs, normal bulbs etc... here is about halogen uses in detailAbove were some unique halogen(s) characteristics. Further we will see some halogen(s) uses according to the halogen elements; fluorine, chlorine, bromine, astatine and iodine.Bromine Uses:Bromine was discovered in 1826 by French and German scientist named Antoine J. Balard and Carl J. Lowig respectively. Bromine is a reddish colored liquid which has a strong odor. It is in liquid form at room temperature and it gives off vapor freely. Bromine has an affinity to hydrogen, which makes it a good decomposer. Bromine is also used to disinfect water as it can kill the bacteria present in the water. The inorganic form of bromine is used in photography film, bromine is also used in fumigants, flame proofing agents, dyes and medicines.Astatine Uses:The word astatine is derived from the Greek word 'astatos' which means unstable. Astatine was discovered by University of California in 1940. It is solid at room temperature. One of the special characteristics of astatine is that it is not found in nature at all! It is produced by bombarding bismuth with alpha particles. The uses of astatine are not yet discovered.Fluorine Uses:Fluorine was discovered by Karl Scheele in 1771 and the word fluorine was derived from the word flow. It is in gaseous form at room temperature, which is said to be highly poisonous. There are many uses of fluorine such as making refrigerants, detergents etc. Fluorine is used mainly for producing uranium form hexafluroide and it is also used for making other fluorine compounds.Earlier, fluorine was used to produce CFC's and these CFC's were used in aerosol sprays, cleaning agents and polymers. However it was found that these compounds can cause ozone layer depletion and so were banned. Other fluorine uses are as: it is used in rocket fuels as it is combustible. The most common of fluoride is in toothpaste. They are used in toothpaste because they are said to avoid dental cavities. In some countries, fluorine is added to municipal water supplies to reduce teeth decay. Fluorinated compounds can be used to create plastic and also for glass etching. Fluorinated compounds are not only used for decorative etching but also for marking glass bulbs as they are too thin to be etched.Chlorine Uses:Chlorine was first found by a Swedish chemist named Wilhelm Scheele in 1774. Chlorine is found in gaseous form at room temperature, it has a pungent and irritating odor and is yellowish green in color. More on chlorine facts. The most important use of chlorine is as a bleach for manufacturing paper and cloth. Chlorine is one of the most commonly manufactured chemicals in the United States. The most common use of chlorine is in drinking water and swimming pool as it can kill harmful bacteria. Further uses of chlorine include production of everyday products such insecticides, solvents, food paints, plastic, dyes, textiles, petroleum products, paper products etc.Iodine Uses:Iodine is a very important element and has a lot of uses. The compounds are basically used in medicine, photography and dyes. Iodine forms starch which is an intense blue complex compound. Another very important use of iodine is as it is quite radioopaque, it can be used as X-ray radio contrast agent, for intravenous injection. Besides this iodine forms many compounds like potassium iodide which is of commercial use, and as sodium iodide which is useful in Finklestein reaction. Read more on Iodine: The Element.These were the halogens uses. Do you still have this question flashing your mind 'What are halogens used for?'' Well, the answer is halogens are also used in lighting halogen bulbs!
How does the toxicity of chlorine and iodine make them useful?
They kill bacteria. Tincture of iodine (Na+I3- in H2O) kills bacteria in human wounds. Chlorine kills bacteria is swimming pools, water treatment plants, and campers' water treatment tablets.They're used to disinfect things, i.e., their toxicity to bacteria is something we can take advantage of. Cl is used in bleach, and I is used in surgical disinfectant.
What is iondine solution?
Iodine is a nonmetallic chemical element which is found abundantly in seawater and in some minerals in the earth. It is classified in the halogens, along with elements like chlorine and bromine, and like other elements in this group, iodine is reactive and toxic in large amounts. There are a number of useful applications for iodine, especially in the field of medicine, and the element is also a vital trace element needed for proper human nutrition.
Why is halogen elements not useful?
This question is based on chemistry. Halogens are useful elements. There are 5 halogens in the world.
What are halogens used for?
Fluorine: There are many uses of fluorine such as making refrigerants, detergents, it is even used as a compound in toothpaste. Chlorine: Chlorine as most people know is used to clean pool water. When people go swimming it is not uncommon for them to say it smells of chlorine. The most important use of chlorine is as bleach for manufacturing paper and cloth. Chlorine is one of the most commonly manufactured chemicals. Chlorine is also used for the production of everyday products such insecticides, solvents, food paints, plastic, dyes, textiles, petroleum products, paper products. It is far more widely used than we realise. Bromine: Bromine is a reddish coloured liquid which has a strong odour. It is in liquid form at room temperature and it gives off vapour freely. It is a good decomposer and is used in photography film, fumigants, flame proofing agents, dyes and medicines. Iodine: Iodine is a very important element and has a lot of uses. The compounds are basically used in medicine, photography and dyes. Another very important use of iodine is as it is quite radio opaque, it can be used as a contrast to X-rays. Astatine: Finally the last halogen and the least common one was only discovered recently and as of yet its uses are not known to us because it is not formed naturally like the other halogens are it has to be changed in a laboratory. Of course the obvious answer is that halogens are used in lighting halogen light bulbs.
What is the most abundant and useful halogen?
* Fluorine is found on Earth at about 585 mg/kg (crust) 1.3 mg/liter (ocean) * Chlorine is found on Earth at about 145 mg/kg (crust) 19400 mg/liter (ocean) * Bromine is found on Earth at about 2.4 mg/kg (crust) 67.3 mg/liter (ocean) * Iodine is found on Earth at about 0.45 mg/kg (crust) 0.06 mg/liter (ocean) * Astatine is not found on Earth in appreciable quantities (it has no stable isotopes) Earth's crust is about 8.5 * 1020 kg Earth's ocean is about 1.4 * 1018 liters This make fluorine the most abundant halogen *on Earth*, with chlorine 30% as abundant by mass, and 16% as abundant in number of atoms. Fluorine only has one stable isotope, whereas chlorine has two. Otherwise the race would not be even that close.
What is a poisonous but useful element?
