Answer:

Of elemental iodine......?

Explanation:

Of course, elemental iodine is ZEROVALENT, i.e. #stackrel(0)I_2#. In its compounds, iodine can assume oxidation states of #-I, 0, +I.....+V,... +VII#; the #+VII# oxidation state occurs in the interhalogen, #IF_7#, and in salts of periodate.... #IO_4^(-)#

Answer:

Iodine has multiple possible valances

Explanation:

Iodine when it combines with a metal or an element with low electronegativity becomes -1 This is iodines preferred valance.

When Iodine combines with a non metal with a high electronegativity its valances become positive.

#I_2O_2 # periodineoxide Iodine has a valance of +1

# IO^-1 # Iodine has a valance of of +1 hypo iodious ion

# IO_2^-1# iodine has a valance of +3 iodious ion

# IO_3^-1# iodine has a valance of +5 iodonic ion

# IO_4^-1# iodine has a valance of +7 hyper iodonic ion

Because Iodine has 7 valance electrons it has multiple possible valance numbers
