Punctuation to for inline word definition

Can someone advise the correct punctuation for the below sentence?

'In https://en.wikipedia.org/wiki/Electrolyte, such as https://en.wikipedia.org/wiki/Saline_water, the charge carriers are https://en.wikipedia.org/wiki/Ion, atoms or molecules that have gained or lost electrons so they are electrically charged.'

The definition for ions is provided inline, for which I believe an alternate punctuation mark that a coma should be used.

Which punctuation would better indicate that 'ions' is being defined with the subsequent text, rather than appearing to present a list of 3 states (ions, atoms or molecules)?

Should it be:

[1] "In https://en.wikipedia.org/wiki/Electrolyte, such as https://en.wikipedia.org/wiki/Saline_water, the charge carriers are https://en.wikipedia.org/wiki/Ionatoms or molecules that have gained or lost electrons so they are electrically charged";

[2] "In https://en.wikipedia.org/wiki/Electrolyte, such as https://en.wikipedia.org/wiki/Saline_water, the charge carriers are https://en.wikipedia.org/wiki/Ion(atoms or molecules that have gained or lost electrons so they are electrically charged)";

[3] or another structure?
