Iodine is a halogen (group 7 of the Periodic Table), and halogens are supposed to have seven valenced electrons to match the amount of protons in their nucleus. However, in order to form a full octet of valence electrons, iodine atoms are willing to accept one more electron. This electron brings iodine's charge down to -1. And unlike other halogens that are smaller than iodine (fluorine, chlorine, and bromine), iodine is large enough so that its negative charge can be distributed more evenly. This makes iodine stable with a negative charge, and a good leaving group in chemical reactions (something you will probably learn later on in organic chemistry).

∙ 13y agoIt isn't - it is neutral - but when ionized becomes -2. This is because of its position in the periodic table. It wants to become a stable Neon type structure - 10 electrons - to do this it needs to acquire 2 electorns and hence it will become -2 charge when ionized

Does iodine form a cation or a anion?
Iodine forms the iodide ion. It has a charge of negative 1 (-1)
Why these iodine form an ion with a charge of -1?
iodine has 7 electrons in the valence shell. and needs one more electron to attain stable noble gas configuration. So it gains one electron and forms iodide ion with charge of -1.
What is the net charge of an iodine ion containing 53 protons 74 neutrons and 54 electrons?
The net charge is -1 (minus 1).
How many iodine ions are needed to balance out a barium ion?
A barium ion has a charge of 2+ and an iodide ion has a charge of 1-, therefore, two iodide ions are needed to balance the barium ion. Ba2+ + 2I- --> BaI2
What is the name of an iodine ion?
An iodide ion is an iodine atom with a −1 charge. Compounds with iodine in formal oxidation state −1 are called iodides. This can include ionic compounds such as caesium iodide or covalent compounds such as carbon tetraiodide.
What will the charge be on an ion formed from iodine?
as ions they are named Iodide.... charge is -1
What is the charge of ions formed from the atom of iodine?
Iodide is monovalent anion. It is I+The charge of the iodide ion is 1-

What is the formula for the ionic compounds K and I?
The ion for Potassium has a charge of 1+.The ion for Iodine has a charge of 1-.This means that in order to make the overall charge of a unit of a compound of Potassium and Iodine, there must be one atom of Potassium and one atom of Iodine.Therefore, when K+ and I- are bonded, they make the ionic compound of KI.

If an atom of iodine gains an electron what is the charge of the resulting ion?
5p
What is the charge on the lead ion in PbS2?
Lead being a transition metal has two possible charges: +2 or +4.
Does iodine lose electrons and form a positive ion?
Iodine typically gains an electron to form a -1 ion.
