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 … Web2 sep. 2012 · People. Cool down. Let's not hurt each other's feeling here. Let me clarify what my professor said and what I'm confused about. He said that along the period anions become more stable due to increased electronegativity along the period. In addition he said that down the group anions become more stable because of increased charge size.

Web10 aug. 2024 · Ionization energies increase moving from left to right across a period (decreasing atomic radius). Ionization energy decreases moving down a group (increasing atomic radius). Group I elements have low ionization energies because the loss of an electron forms a stable octet. Electron Affinity WebA higher effective nuclear charge causes greater attractions to the electrons, pulling the electron cloud closer to the nucleus which results in a smaller atomic radius. Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital. This results in a larger atomic radius. 2.
