Gia Black · Answer 1

the ion with the most electrons

Explanation:

Ionic size generally depends on weather the ions are negative or positive. Averagely, atoms become smaller on moving from left to right in the periodic table. A movement from left to right in the periodic table leads to a gradual increase in the number of electrons and decrease in atomic size. Li+, Be2 + and B3 + are all isoelectronic but B3 + is the smallest ion.
