What is this statement called:  “Each orbital of a given sublevel must be occupied by a single electron having the same spin before pairing of the electrons begins.”

Which of these is paramagnetic? Consider whether electrons are paired or not.

What are the spectator ions if sodium phosphate reacts with barium nitrate to give barium phosphate and sodium nitrate? HINT: Start with a balanced equation showing (s) for the precipitate, if any.

Which of these is paramagnetic? Consider whether electrons are paired or not.

Which term is used for a chemical equation in which those ions and molecules actually involved in the reaction are shown, but any spectator ions are omitted.   Example:    Ag+   +   Cl-     AgCl(s)
