Who discovered ions?

Michael Faraday
The existence of ions was first theorized by Michael Faraday around 1830, to describe electrically charged atoms or groups of atoms that traveled toward an anode (positively charged electrode) or cathode (negatively charged electrode).

How many ions are in NaCl?

The ions present in NaCl is one ion of Na and one ion of Cl.

How are ions names?

Ionic compounds are named by stating the cation first, followed by the anion. Positive and negative charges must balance. Some anions have multiple forms and are named accordingly with the use of roman numerals in parentheses. Ternary compounds are composed of three or more elements.
