Anions and Cations OH My!!! Anions are Negative Ions A Negative ION = ANION Cations are Positive Ions ca + ions (meow)
An anion (-) (pronounced æn.a ɪ.ən or an- eye-ən), from the Greek word νω (ánō), meaning "up", is an ion with more electrons than protons, giving it a net negative charge. A cation (+) (pronounced kæt.a ɪ.ən or kat- eye-ən), from the Greek word κατά (katá), meaning "down", is an ion with fewer electrons than protons, giving it a positive charge.
