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.

Given Mg (CO3) 2, CO2 and Cu3 (PO4) 2, provide the names for each of these molecules.

How does probability fit into the description of the atom?

Copper conducts electricity, while sugar, C6H12O6, does not. Can you explain why this is so in terms of structure and/or bond types.
