It depends on what kind of ion:
- If it's a cation (H+) then there is 1 proton and 0 electrons, so zero.
- If it's an anion (H-) then there is 1 proton and 2 electrons, so 2 (and that shell is full).

How many valence electrons will hydrogen have after chlorine steals electrons?
The hydrogen ion H+ is without electrons.
How many valence electrons does magne sium have?
A magnesium atom has 2 electrons in its valence shell. A magnesium ion has 8 electrons in its valence shell.
Does H and HE have the same valence electron configuration?
Hydrogen and helium have different valence electron configurations. Hydrogen has one valence electron, and helium has two valence electrons. However, hydrogen does typically form covalent bonds in which it shares an electron, and thereby gains an effective electron configuration of two, like helium. Hydrogen also can form the H+ ion which has no electrons.
Why is o6 a helium like ion?
Helium has two valence electrons. O6+ ion (a hypothetical ion) will also have 2 valence electrons.
How many valence electrons do halogens gave?
Halides have 7 valence electrons, but the halide ion, haven gained an electron has 8 valence electrons
How many valence electrons will hydrogen have after chlorine steals electrons?
The hydrogen ion H+ is without electrons.
How many valence electrons are in a chlorine atom and a chloride ion?
There are 7 valence electrons in chlorine atom and 8 valence electrons in chloride ion.
How many valence electrons are present in a chloride ion?
A chloride ion has 18 electrons, giving it a valence of -1.
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 valence electrons are in the polyatomic ion HPO4 -2?
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.
How many valence electrons in arsenide ion?
Three electrons
How many valence electrons are in chloride?
Chlorine has 7 valence electrons. A chloride ion has 8.
How many valence electrons does magne sium have?
A magnesium atom has 2 electrons in its valence shell. A magnesium ion has 8 electrons in its valence shell.
What the total number of electrons in the Lewis structure for the C2H3O2- ion?
Carbon has 4 valence electrons; hydrogen has 1; oxygen has 6. As it is a negative (1) ion, you add 1 valence electron. (4)(2)+(1)(3)+(6)(2)+1=24 valence electrons
How many electrons are in a phosphorus Ion's outermost energy level?
Phosphorus forms P3- ion and it has 8 valence electrons (5 valence electrons from phosphorus and three from the charge).
How many valence electrons are in a stable nonmetal ion?
8
Does H and HE have the same valence electron configuration?
Hydrogen and helium have different valence electron configurations. Hydrogen has one valence electron, and helium has two valence electrons. However, hydrogen does typically form covalent bonds in which it shares an electron, and thereby gains an effective electron configuration of two, like helium. Hydrogen also can form the H+ ion which has no electrons.
