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.
How is an iodine ion named?
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.
How many valence electrons are there in an atom of arsenic iodine calcium tin and sulfur?
What kind of question is that lol I don't even know that and I just studyed that last semester lol
Why is the ion charge of iodine -1?
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).
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.
How many electrons will be in the valence shell of a iodine ion?
Iodine atom has 7 valence electrons, whereas Iodide ion has 8 valence electrons.
What is the number of valence electrons of iodine?
Iodine has 7 valence electrons. It is in Group 17 of the periodic table, also known as the halogens, which have 7 valence electrons.
How many valence electrons in iodine?
7 valence electrons in iodine
How many valence electron does an iodine have?

How many valence electrons does iodine pentafluoride have?
Iodine pentafluoride has 7 valence electrons.
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.
If an atom of iodine gains an electron what is the charge of the resulting ion?
5p
If an atom of iodine gains one electron it will have the same number of valence electrons as which element?
The same number of valence electrons as xenon.
How many valence elections are transferred from the calcium atom to iodine in the formation of the compound calcium iodine?
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
