The anion formed from an oxygen atom is called a (n) a. oxygen ion. c. carbon dioxide. b. oxide ion. d. nitrous oxide.

These values also increase from the bottom to the top of a group because the size of the atom decreases, resulting in a distance between the nucleus and the valence electron shell, which increases the attraction between the protons and electrons.
