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 in arsenide ion?
Three 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).

8
Why is o6 a helium like ion?
Helium has two valence electrons. O6+ ion (a hypothetical ion) will also have 2 valence electrons.
What is the difference between the chlorine ion and the chlorate ion?
An atom is a neutral particle with the same number of protons as electrons. Ions are particles that have either more or less electrons. Ions can be positively charged (cations) or negatively charged. Ions will lose or gain electrons in order to have eight outer shell electrons. A chlorine atom has 17 electrons and 7 valence electrons (outer shell). It "wants" to have eight valence electrons, so it will gain one. Therefore, the typical chlorine atom will have one electron more.
How many valence electrons do halogens gave?
Halides have 7 valence electrons, but the halide ion, haven gained an electron has 8 valence electrons
What are valence electrons and where can they be found?
Electrons in the outermost shell of an atom/ion are called valence electrons
