 "Health is real, like it or not, and without scientists, the world health will deteriorate. Your health can not be secured with elements like gold, but Iodine! That can be a life saver."



Status update:

1818: It's about time! Finally in France Bernard Courtois discovered me! For all my medical uses, you'd think they'd want me sooner.

1830: Hasta Lavista Goiter! Scientists discovered that I'm great for preventing goiter.

March 2006: My deficiency is still a public health problem.

11/4/13: When Bromine and I reacted in the equation: I2 + Br2 → 2 IBr   Despite all the changes we went through, we didn't lose mass like the Law of Conservation of Mass states.


My Atomic Number is 53, my atomic symbol is "I" and I'm in the halogen group. I am a shiny silver solid at room temperature. When I'm heated to a gas I am a rich purple color. I was discovered by Bernard Courtois in France. I dissolve readily in chloroform and dissolve slightly in water.



Relationship Status: 

11/4/13 In a relationship

Primary Relationship: 

Bonded with Bromine


I'm in the non-metal network

valence electrons:

I have seven valence electrons

reactivity: I am less reactive, less than other halogens. Commonly combines with Alkali metals, including Potassium creating Potassium Iodine.
state of matter:  I'm solid at room temperature 
Location on Periodic Table: Group 17 Period 5 


 I was discovered in 1811


I was discovered by Bernard Courtois in France 


Dora's journey to the planet Iodine: A very Purple Situation 

Activities & Interests:

One of my uses is Radiation Exposure, because I help reduce the harmful accumulation of radioactive substances in the thyroid. Another one of my uses is my purpose as a sterilizing agent when it's used to clean wounds and to purify water. Nascent atomic iodine supplemants boost overall thyroid health and prevent Goiter. Goiter is  the throat area and thyroid gland.


I react with air, water, halogens, acids, and bases. That doesn't leave any room for things I don't react with.



10/18/13 Checking at the Northside Hospital for a blood drive, lots of people need their arms cleaned.

12/31/13 Vegies, wow, people sure like there leafy greens salty! 

7/4/13 I love the beach! All this salt water in the ocean is a great place for me!

11/4/13 Checking in after reacting with bromine: I2 + Br2 → 2 IBr

This is when I was heated to a liquid before turning into a gas.

You can go to get something and read all about me too. 

Wow! I'm like a rainbow! 

I like things salty, too bad she's dropping it on the ground! 

Never thought I'd see the guys that found me first!

How much Iodine does a person need per day?

iodine said

at 6:31 pm on Oct 28, 2013

The average adult should receive 150 micrograms of Iodine per day; the Iodine can come from a variety of sources.

What oragan in the human body uses iodine and what does it regualte?

iodine said

at 9:52 am on Oct 29, 2013

The thyroid gland is the organ that depends the most on iodine. However, practically all organs need iodine including the stomach.

Whate ailments are associated with iodine deficiency?

iodine said

at 9:47 am on Oct 29, 2013

Iodine deficiency can cause inflammation on the thyroid gland resulting in swelling in the neck and larynx regions. Stomach lining cells require iodine and the lack on iodine in these tissues increase the risk of stomach cancer.

Hey! Did you know that together we form actinium triiodide? We should meet up sometime and hangout!

cesium said

at 9:12 am on Oct 29, 2013

Hey... would you like to join my secret service? If we bond, we'll make CsI, or Cesium Iodide! How does that sound?

uranium said

You want to bond together? We'll have a blast!!

stontium said

at 3:25 pm on Oct 29, 2013

Hey! I know other people are asking, but trust me, we'd be the best if we'd bond!!

gold said

at 3:55 pm on Oct 29, 2013

Hey... I know these people have been asking to combind with you, but you obviously know gold is the best! We will bond so well together!
iodine+gold= together forever<3

combine*** I'm sorry, I get flustered when I'm thinking of attractive elements

iodine said

I like my money (gold) to spell things right and to be educated. I don't know if this will work out.

cobalt said

Hey what is up Iodine! We need to hang out sometime and make Cobalt iodide. It's used to indicate humidity and moisture. It'll be an interesting hangout. (:

neodymium said

at 11:01 am on Nov 3, 2013

You wanna bond together we make Neodymium III

europium said

at 6:46 pm on Nov 4, 2013

Hey iodine together we form Europium Iodine, we should get together. How many people can say that they are with a lanthanide.

iodine said

at 8:10 pm on Nov 4, 2013

In a covalent bond with Bromine to make Iodine Bromide. Together we form an interhalogen, so now we can rule the interhalogen galaxy!
