WebHistory of discovery. 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 … Web23 nov. 2024 · As the size of halide increases down the group, the lattice energy decreases. This is because with the increase of size of ions, the distance between their nuclei increases. Thus the attraction between them decreases and finally the less lattice energy released during the process. b) Charge of ions
