However when considering ions, you do have to think distinctly about cations and anions. Calcium forms a positively charged +2 cation. Chlorine forms a negatively charged -1 anion.

Explore the differences between cations and anions, their roles in chemical reactions, and their placement on the periodic table. Learn more now.

Dual-ion batteries (DIBs), in which both cations and anions are involved in the electrochemical redox reaction, are one of the most promising candidates to meet the low-cost requirements of ...
