A chlorine ion with a stable arrangement of eight valence electrons is called a chloride ion (Cl-). It achieves this stable arrangement by gaining one electron from another atom to fill its outermost electron shell.

How many valance electrons do fluorine and chlorine have?

Since fluorine and chlorine are in family 7A, they each have 7 valence electrons. The number of the family corresponds to the number of valence electrons.


How many valence electrons does chlorine have?

Chlorine has seven valence electrons. The electronic configuration is 1s2, 2s2, 2p6, 3s2, 3p5. These seven valance electrons do NOT readily react, because they are 'tightly' held to the nucleus. However, chlorine has strong electron affinity; Electronegativity; this means it will attract one electron into its valance shell , to complete the octet of eight electrons in the valance shell. When this 'extra' electron combines into to valance shell , the electron configuration is 1s2, 2s2, 2p6, 3s2, 3p6. , and the chlorine atom is now a 'CHLORIDE ANION' of charge '-1' , (symbolised by Cl^(-)).


How many electrons do chlorine oxygen and nitrogen have?

Nitrogen has 7 electrons, oxygen has 8 electrons, and chlorine has 9 electrons. That is the total electron count, for inner and outer shells. If you are only concerned with the valance electrons, then it is 5 for nitrogen, 6 for oxygen, and 7 for chlorine.


How many electrons does chlorine have on the outer shell?

chlorine has 6 electrons in the outer shell. although these have a special name, they are called valance electrons.


Which subshell of chlorine have valence electron?

3s and 3p, remember Cl has 7 valance electron. 3s^2 and 3p^5


Does chlorine have 6 electrons?

it has 6 valance electrons, the number of electrons can be determined by the number of protons it has, which is the same as it's atomic number.


Is chlorine an electron doner or an acceptor?

Chlorine has 7 valance electrons so the easiest way for it to fill it's valance shell and have an octet is to be an electron acceptor; an anion.


How many valance electrons in Co?

There are 27 valance electrons.


How many valance electrons does samarium have?

2 valance electrons


Number of valence electrons in chlorine?

I think that because chlorine has 17 electrons in all, and ten of them are filled up on the first two shells, then seven of them should be on the third shell, so seven of them are valance electrons.


How can you tell if an element has more valance electrons than other element has from the periodic table?

The groups, or families of elements have the same number of valance electrons and this information can be found at the top of the periodic table. For instance; 1A represents the alkali metals and they all have a valance number of 1. Then go from the left to the right and look at the top of the table. 8A represents the farthest left family of elements, from top to bottom, the Nobel gasses. They have a full valance shell of 8 electrons.
