First you have to find the overall charge of the C2H3O2. Hydrogen always has to have a +1 charge, and oxygen generally gets a -2 charge. then use the x for the unknown and multiply each charge by the number of the substance.
ex. 2(x) [for the carbon] + 3(+1) [for the hydrogen] + 2(-2) [for the oxygen]= overall charge of the molecule. then find x.
In the Lewis structure of the C2H3O2- ion (acetate ion), there are a total of 24 electrons. This includes 12 electrons from the carbon atoms (6 from each carbon), 3 electrons from the hydrogen atom, and 9 electrons from the oxygen atoms. The negative charge adds 2 additional electrons for a total of 24 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 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.

A chloride ion has 18 electrons, giving it a valence of -1.
