There are 18 electrons in a chloride ion.
A chloride ion has gained one electron to become a Cl- ion, making it uncharged overall but with 18 electrons to match the 17 protons in its nucleus.
Chlorine has 7 valence electrons. A chloride ion has 8.
Chlorine has 17 protons and an atom of Chlorine would have 17 electrons. However a Chloride Ion will have one more electron ie 18 electrons and will be negatively charged.
A chloride ion has gained one electron to achieve a full outer shell and achieve a stable electron configuration. Therefore, a chloride ion has 18 electrons.
In the question, it should be either "chlorine atom" or "chloride ion". Chlorine atom has 7 valence electrons. Chloride ion has 8 valence electrons.
The chloride ion has eight valence electrons.
8
A chloride ion has 18 electrons, giving it a valence of -1.
No. By definition an ion is electrically charged and so must have a different number of protons and electrons. A chloride ion has 17 protons and 18 electrons.
The chloride ion in table salt has 8 electrons in its outermost energy level. This is because it has gained an extra electron to achieve a full octet of 8 electrons, making it a stable, negatively charged ion.
In vanadium III chloride (VCl3), the vanadium ion has a charge of +3, meaning it has lost 3 electrons. Each chloride ion (Cl-) has gained 1 electron. So there are a total of 3 electrons in VCl3 - one from each Cl ion.
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.
