Question about the name of I2
« on: March 25, 2015, 08:43:34 AM »
Hello, I am currently trying to find more (english) information about I2 on the internet.
The problem is I don't know how I2 is called in english, I know "I" is iodine but what about "I2" ?

In french we call "I" Iode and "I2" Diiode but I can't find the equivalent word in english for "diiode"
How do english speakers make the difference between the two ?

Sorry for this trivial question.

Iodine exist as I2, so there is no different name.

Read here in the middle of the article: http://en.wikipedia.org/wiki/Iodine

It is sometimes referred to as "elemental iodine" or "molecular iodine", but in English I2 is normally just "iodine".

A problem you might have with your internet searches is that "iodine " is a term often used in nutritional literature to refer to "dietary iodine", which is usually in fact iodide.

What sort of information are you looking for, maybe we can point you in the right direction?

And who decided the bizarre naming of "dioxygen", "dihydrogen" and more? The French school system? The French Wiki tells "diiode", the English and German don't, the Spanish only for unusual emphasis.

Because, well, trioxygen is uncommon enough that we can use a different word for it, say as well "atomic hydrogen" when its not diatomic - and keep the short name for the overwhelmingly predominant form.

I am looking how to prepare molecular/elemental Iodine. By any chance do you know a good paper or article about it ?

Once again, thank you for the help.
