8 because sulfur has 6 valence electrons and when it becomes sulfide it gains two electrons making it 6+2=8.
There are two lone pairs of electrons on the sulfur atom in the sulfite ion. This is because sulfur is in group 16 of the periodic table and has six valence electrons, two of which form a double bond with one of the oxygen atoms in the sulfite ion.
Arsenide ion has 3 valence electrons. Arsenic, the element from which arsenide ion is derived, is in group 15 of the periodic table, so it has 5 valence electrons. When it forms an ion with a charge of -3, it gains 3 electrons to achieve a full octet.
A sulfur atom has 6 valence electrons, while a sulfide ion has 8 valence electrons because it gains two electrons to achieve a stable electron configuration.
A chlorine atom has 7 valence electrons, as it is in group 17 of the periodic table. A chloride ion has 8 valence electrons, as it gains an additional electron to achieve a full octet and a stable electron configuration.
Iodine atom has 7 valence electrons, whereas Iodide ion has 8 valence electrons.

Chlorine has 7 valence electrons. A chloride ion has 8.
if you are asking about ICl4- ion then there are 28 valence electrons and 8 binding ones.total of 36 electrons
Arsenide ion has 3 valence electrons. Arsenic, the element from which arsenide ion is derived, is in group 15 of the periodic table, so it has 5 valence electrons. When it forms an ion with a charge of -3, it gains 3 electrons to achieve a full octet.
A magnesium atom has 2 electrons in its valence shell. A magnesium ion has 8 electrons in its valence shell.
A sulfur atom has 6 valence electrons, while a sulfide ion has 8 valence electrons because it gains two electrons to achieve a stable electron configuration.
A chlorine atom has 7 valence electrons, as it is in group 17 of the periodic table. A chloride ion has 8 valence electrons, as it gains an additional electron to achieve a full octet and a stable electron configuration.
Iodine atom has 7 valence electrons, whereas Iodide ion has 8 valence electrons.
Sulfur (S) has 6 valence electrons. The S2- ion gains two electrons, bringing the total to 8 valence electrons.
Hydrogen has 1 valence electron, phosphorus has 5 valence electrons, and oxygen has 6 valence electrons. So, if you totaled all of the valence electrons in the ion HPO42- you'd get 1 + 5 + 6 X 4 + 2 = 32. However, you should realize that the term "valence electron" really only applies to individual atoms, not compounds. The only electrons one would concern themselves with in the HPO42- ion are the 2 that make it an ion.
8
A chloride ion has 18 electrons, giving it a valence of -1.
