Which ions-positive ions or negative ions-tend to be larger and why?
A)Positive ions because they have more protons
B)Positive ions because they have more electrons
C)Negative ions because they have more neutrons
D)Negative ions because they have more electrons

Question

Quizplus · Accepted Answer

Negative ions tend to be larger because they have gained electrons, increasing their electron cloud and creating a greater repulsion between electrons, leading to an increase in size. Positive ions would have lost electrons, reducing their electron cloud and making them smaller, but the number of protons is not the determining factor in ion size. Neutrons do not affect ion size as they do not have a charge.
