Potassium ion has 18 electrons.
The H+ ion has no electrons.
flouride atoms are part of the halogen group and so have 7 valence electrons. however a flouride ion is a different story. firstly it depends if the ion is an anion or a cation. if the ion is F- then it is an anion and has 1 extra electron and so has 8 valence electrons. if it is F+ is is a cation and has lost an electron and so has only 6 valence electrons. if the ion is F2- this means it has gained two electrons and so on.
Chlorine will not for Cl-7 ion. It will form Cl-1 ion, which has total of 18 electrons.
electrons have negligible mass. the mass of the ion depends on how many protons and neutrons are present.
There are 18 electrons in a chloride ion.
a cuprous ion has 28 electrons.
The ion Fr+ has 86 electrons.
Potassium ion has 18 electrons.
There are 10 electrons in an Mg2+ ion.
The chloride ion has 18 electrons.
The H+ ion has no electrons.
18 electrons
The ion S(2-) has 16 protons and 18 electrons.
A chlorine ion is monatomic ― it is just Cl-.

None.Calcium loses 2 electrons to form an ion.
