Chloride ion like the chlorine atom has seventeen(17) protons.
In an atom the number of protons and electrons is equal.
However, in an ion the number of protons remains the same, BUT THE NUMBER OF ELECTRONS is different.
So for chlorine atom there are 17 protons and 17 electrons.
However, the chloride ion there are 17 protons and 18 electrons.
This difference is indicated by 17(+) & 18(-) or
(+)17 - 18 = -1 . So the chloride ion symbol is written as 'Cl^(-)'. The 'one' is never shown.
NB A negative ion is given the name ' ANION;,
NNB Do not confuse with 'Neutrons'. Different numbers of neutrons are referred to as ISOTOPES. Chlorine exhibits two principal isotopes. They are Chlorine-35 and Chlorine-37. Overall the proportions of these two isotpes is such that chlorine is given the Atomic Mass of 35.5. However, the number of protons remains the same at '17', and the number of electrons can still vary between the two isotopic atoms and ions.

How many chloride ions in silver chloride?
Silver chloride is AgCl, that is one Ag+ and one Cl- , ionically bound together.
If chlorine forms a 1- ion. How many electrons does a chloride ion have?
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.
What is the colour of chloride ion?
Chloride ion is colorless.
How many chloride ions are in one formula unit of nacl?
There is only one chloride ion in the formula unit of sodium chloride.
How does a chlorine atom change into a chlorine ion?
A chlorine atom gains an electron to become a chloride ion. This extra electron gives the ion a negative charge, balancing the positive charge of the proton in the nucleus, resulting in a stable electron configuration.

Chlorine forms a 1- ion How many electrons does a chloride ion have?
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.
How many chloride ions are in one formula unit of nacl?
There is only one chloride ion in the formula unit of sodium chloride.
How many atoms are there in chloride ion?
Only 1.
How does a chlorine atom change into a chlorine ion?
A chlorine atom gains an electron to become a chloride ion. This extra electron gives the ion a negative charge, balancing the positive charge of the proton in the nucleus, resulting in a stable electron configuration.
What will be the charge for chlorine when it becomes ions?
A chlorine ion will have a charge of -1. A chlorine atom gains one electron to form the more stable chloride ion, thereby incurring a charge of -1. There is now one more electron than proton in the chloride ion, as compared to the chlorine atom which is electrically neutral.
