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.
Silver chloride is AgCl, that is one Ag+ and one Cl- , ionically bound together.
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.
Chloride ion is colorless.
There is only one chloride ion in the formula unit of sodium chloride.
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.
There are 18 electrons in a chloride ion.
All isotopes and ions of hydrogen have one proton.
8 proton
The hydroxyl ion is OH and isn't a proton.
Silver chloride is AgCl, that is one Ag+ and one Cl- , ionically bound together.
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.
Chloride ion is colorless.
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.
There is only one chloride ion in the formula unit of sodium chloride.
Only 1.
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.
A proton.
