1. For each statement select P for Positive, N for Negative, or Z for Zero charge (Neutral). (If the first answer is positive, the second negative, and the third neutral (zero net charge), enter PNZ. Do not enter spaces) A) A negatively charged rod is brought close to a neutral isolated conductor, but it does not touch. The conductor is then grounded while the rod is kept close. If the ground connection is first broken, and THEN the rod is...

match up the correct formula and magnetic property. which pair
is correct
The theory considers covalent interactions between a metal center and surrounding ligands. The theory considers electrostatic interactions between a metal ion and the surrounding ligands which are taken to be point charges. The theory rationalizes the non-degeneracy of the metal d orbitals by considering the electrostatic repulsions between point charge ligands and electrons in the metal d orbitals. The theory rationalizes why the metal d orbitals are split...
