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 many core electrons in an Iodine atom?
I am not positive what you mean by "core electrons" but: 57 (total) 7 (valence, outermost) 50 (non-valence, everyone but valence)
What is the valency for iodine?
Iodine's atomic number is 53. That puts it in the halogen group. All halogens have 7 valence electrons.
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.
Why do the valence electrons in nitrogen experience a greater effective nuclear charge than the valence electrons in beryllium?
valence electron in nitrogen
What is the number of valence electrons of iodine?
Iodine has 7 valence electrons like the other halogens.
How many valence electrons in iodine?
7 valence electrons in iodine
How many valence electron does an iodine have?
Seven valence electrons in iodine.
If an atom of iodine gains an electron what is the charge of the resulting ion?
5p

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.
How many electrons would be in the valence shells of iodine and chlorine?
Both iodine and chlorine are halogens (group 17) and have 7 valence electrons.
Rank the element carbon sodium calcium and iodine in order of decreasing number of valence electrons?
The order is: Iodine (7 valence electrons) Carbon (4 valence electrons) Calcium (2 valence electrons) Sodium (1 valence electron)
How many valance election does an iodine atom have?
An iodine atom has seven valence electrons.
Where can you find the valence electrons of iodine?
On the last electron shell; iodine is a monovalent element.
How many valence electrons in a iodine atom?
Seven
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
