Anion
Eletron
A positive ion is formed when atoms lose electrons. When a cell gains an electron it becomes negative
No, the atomic number remains the same when an ion is formed. The atomic number is determined by the number of protons in an atom, which does not change when an atom becomes an ion by gaining or losing electrons.
