18
As the chlorine atom has 17 electrons, the chloride ion has 18.
The chloride ion (Cl-) has 8 electrons on the outermost energy level.
Chlorine is a gas at room temperature; in nature chlorine exist in many chloride minerals or as hydrogen chloride in volcanoes gases.
Two
A chlorine ion is monatomic ― it is just Cl-.
The chloride ion has 18 electrons.
There are 7 valence electrons in chlorine atom and 8 valence electrons in chloride ion.
As the chlorine atom has 17 electrons, the chloride ion has 18.
Chlorine has 7 valence electrons. A chloride ion has 8.
In the question, it should be either "chlorine atom" or "chloride ion". Chlorine atom has 7 valence electrons. Chloride ion has 8 valence electrons.
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.
Cl has 7 valence electrons.
In most of its compounds chlorine forms just one bond, so it has six nonbonding electrons.
Sodium reacts with chlorine to form sodium chloride which is an ionic compound. It has a crystalline structure and has no molecules.
Chlorine atom has 17 electrons. It is readily accepting an electron from another atom to obtain its stable electron configuration (of argon). A chloride ion has 18 electrons.
Cl2 is the diatomic molecule of chlorine (Cl) . It has 14 valence electrons, 7 in each atom. When chlorine forms a chloride ion, an atom accepts an electron and becomes Cl- (negative ion).
There are eight electrons in the outermost energy level of a chloride ion.
