Three electrons
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.
Iodine atom has 7 valence electrons, whereas Iodide ion has 8 valence electrons.
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.
A chloride ion has 18 electrons, giving it a valence of -1.
an ion
A I ion, specifically iodide (I⁻), has a total of 8 valence electrons. In its neutral state, iodine has 7 valence electrons, but it gains one additional electron when it forms an ion, resulting in 8. Since each pair of valence electrons consists of 2 electrons, there are 4 pairs of valence electrons in an iodide ion.
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
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.
Iodine atom has 7 valence electrons, whereas Iodide ion has 8 valence electrons.
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.
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.
Halides have 7 valence electrons, but the halide ion, haven gained an electron has 8 valence electrons
