The valence charge of iodine KIO2 would be negative one. The charge may vary depending on the type if iodine.
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.
An iodine ion is named based on its charge. If it has a -1 charge, it is called an iodide ion. If it has a +1 charge, it is called an iodine ion.
What kind of question is that lol I don't even know that and I just studyed that last semester lol
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).
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.
Iodine atom has 7 valence electrons, whereas Iodide ion has 8 valence electrons.
Iodine has 7 valence electrons. It is in Group 17 of the periodic table, also known as the halogens, which have 7 valence electrons.
7 valence electrons in iodine
Seven valence electrons in iodine.
Iodine pentafluoride has 7 valence electrons.
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.

The same number of valence electrons as xenon.
One calcium atom will transfer one of each of its two valence electrons to one each of two iodine atoms. In the process, the calcium atom becomes a calcium ion with a 2+ charge, and each iodine atom becomes an iodide ion with a 1- charge. The opposite charges between the iodide and calcium ions form an electrostatic attraction called an ionic bond, forming the ionic compound calcium iodide. Ca + I2 ---> I- + Ca2+ + I- ---> CaI2
Iodine has 7 valance electrons
Iodine has 7 valence electrons.
Both iodine and chlorine are halogens (group 17) and have 7 valence electrons.
