What is a matching element for iodine?
These were the first crystals of iodine ever made. Courtois studied this new substance and found that it combined well with phosphorous and hydrogen, but it did not form compounds easily with carbon or oxygen.
What can you not do after radioactive iodine treatment?
First two days:
- Do not share cups, glasses, plates or eating utensils. Wash items promptly after using.
- Do not share towels or washcloths.
- Flush the toilet twice and rinse the sink and tub after use.
- Wash your towels, bed linens, underwear, and any clothing stained with urine or sweat.
Is iodine reactive with other elements?
Iodine is the most electropositive halogen and the least reactive of the halogens even if it can still form compounds with many elements. Iodine sublime easily on heating to give a purple vapour. Iodine dissolves in some solvents, such as carbon tetrachloride and it is only slightly soluble in water.
What is iodine reactive with?
Iodine combines readily with most metals and some nonmetals to form iodides; for example, silver and aluminum are easily converted into their respective iodides, and white phosphorus unites readily with iodine.
What was iodine named after?
violet
| Discovery date | 1811 |
|---|---|
| Discovered by | Bernard Courtois |
| Origin of the name | The name is derived from the Greek ‘iodes’ meaning violet. |
| Allotropes | I2 |
How long does it take to feel better after radioactive iodine?
It usually gets better within 4 to 8 weeks. It can help to drink plenty of fluids after your treatment.
Can I use my cell phone after radioactive iodine?
You will have to stay in your room for at least 1 to 2 hours after your treatment. You can use your cell phone or watch TV to help pass the time. You won’t be able to have visitors during this time. You may not have any side effects from the treatment right after you get it, but you may have side effects later.
How does iodine react with fluoride?
Iodine, I2, reacts with fluorine, F2, at room temperature to form the pentafluoride iodine(V) fluoride. At 250°C the same reaction affords the heptafluoride iodine(VII) fluoride. With careful control of the reaction conditions, (-45°C, suspension in CFCl3), it is posible to isolate the trifluoride iodine(III) fluoride.
What is the flammability of iodine?
Iodine is not combustible, but it is a STRONG OXIDIZER that enhances the combustion of other substances. Use water only. DO NOT USE CHEMICAL or CO2 as extinguishing agents. POISONOUS GASES ARE PRODUCED IN FIRE, including Hydrogen Iodide and other Iodine compounds.
Why is iodine an unusual element?
Iodine is the least reactive of the halogens as well as the most electropositive, meaning it tends to lose electrons and form positive ions during chemical reactions. It is also the heaviest and the least abundant of the stable halogens.
How did iodine get its symbol?
Iodine is found in seawater, as iodide. It is only present in trace amounts (0.05 parts per million); however, it is assimilated by seaweeds. In the past iodine was obtained from seaweed….
