Question

What is the difference between anion, cation,and ion?

Answer 1

Anion is the negative ion, ie having a negative charge. This ion has more number of electrons and less number of protons.

Cation is the positive ion, ie having a positive charge. This ion has less number of electrons and more number of protons.

Ion is an atom with imbalance between protons and electrons, hence giving it a resultant charge, either positive or negative
