The word ion was coined from Greek neuter present participle of ienai (Greek: ἰέναι), meaning "to go". A cation is something that moves down (Greek: κάτω pronounced kato, meaning "down") and an anion is something that moves up (Greek: ano ἄνω, meaning "up"). They are so called because ions move toward the electrode of opposite charge. This term was introduced (after a suggestion by the English polymath William Whewell) by English physicist and chemist Michael F… WebIon carriers can transfer ions from a hydrophilic medium, such as water, into a hydrophobic medium, i.e a biological membrane, where the ions typically would not be soluble. They can do this by binding to particular ions and acting as a mobile carrier, escorting them through the hydrophobic environment of cell membranes, or they can form ion ...
