Why did mendeleev place tellurium before iodine?
Iodine's atomic number is 53 whereas tellurium's is 52. Atomic number is basically the number of protons that an element has. Therefore, as iodine has more protons than tellurium, it appears later in the table.
Which elements are considered halogens?
The halogens are a group of elements in the periodic table that includes fluorine, chlorine, bromine, iodine, and astatine. These elements are highly reactive and form salts when they react with metals.

Any of the group of non metallic elements, fluorine, bromine, chlorine, iodine and astatine. They are missing an electron from their outer most shell and react with most elements to form salts

How can iodine crystal be remove from the mixture?
Iodine crystals can be removed from a mixture by sublimation, where the crystals are heated to turn directly into vapour without melting. The vapour can then be condensed back into solid iodine crystals. This technique allows for the separation of iodine from other components in the mixture.
Which elements help prevents thyroid problems?
Iodine and Selenium are elements that might help prevent thyroid problems, although a doctor should be consulted first before self-administering any supplements.
