Iodine is a non-metallic, dark-gray/purple-
black, lustrous, solid element
. 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.
What is the density of Iodine?
| Atomic number 53 | Density 4.93 g.cm – 3 at 20 °C | Melting point 114 °C | Boiling point 184 °C | Vanderwaals radius 0.177 nm |

Is Iodine a heavy metal?
Iodine, at the right quantity, is a
powerful heavy metal chelator
, meaning that it binds to heavy metals, helping to remove them from the body through the urine.
Which elements have the highest density?
Values are shown relative to
osmium
, the element with the highest density.
Is iodine very reactive?
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 much iodine do we need daily?
How much iodine do I need? Adults need
140 micrograms (μg)
of iodine a day. Most people should be able to get all the iodine they need by eating a varied and balanced diet.
How can I tell if I am allergic to iodine?
- itchy rash that comes on slowly (contact dermatitis)
- hives (urticaria)
- anaphylaxis, which is a sudden allergic reaction that can cause hives, swelling of your tongue and throat, and shortness of breath.
Does iodine cleanse the blood?
Your blood cells pass through your thyroid glad
every 17 minutes
and help purify your blood when a healthy volume of iodine is present. Hospital emergency rooms and operating rooms use iodine in the form of 10% povidone-iodine (name brand Betadine solution).
Is iodine bad for your liver?
Few case reports have found that iodine-131
induced liver injury
, including a case report involving a patient with Grave’s disease [4,5]. Here we present a case of drug-induced liver injury (DILI) that occurred 10 days after iodine-131 ablative therapy and responded favorably to oral corticosteroid.
What are the 3 most dense elements?

What is the most dense thing in the universe?
At the modest temperatures and pressures of Earth’s surface, the densest known material is the
metallic element osmium
, which packs 22 grams into 1 cubic centimetre, or more than 100 grams into a teaspoonful.
What is the least dense solid?
The world’s least dense solid is
a graphene aerogel
with a density of just 0.16 mg/cm3; produced by a research team from the Department of Polymer Science and Engineering lab at Zhejiang University, China, headed up by Professor Gao Chao (China).
What are 3 uses of iodine?
Today, iodine has many commercial uses. Iodide salts are used in
pharmaceuticals and disinfectants, printing inks and dyes, catalysts, animal feed supplements and photographic chemicals
. Iodine is also used to make polarising filters for LCD displays.
What is iodine used for medically?
Iodine is taken by mouth to
prevent and treat iodine deficiency
and its consequences, including goiter and some thyroid disorders. It is also used for treating lumpy breasts (fibrocystic breast disease) and breast pain (mastalgia).
What is iodine toxicity?
Iodine toxicity is
a rare condition that requires a broad initial diagnosis and heightened suspicion
. These patients may exhibit vague signs and symptoms such as nausea, vomiting, and diarrhea. While history taking may reveal the toxicity, the cause is difficult to determine without further evaluation.
