Question

14. The rule that an orbital can h opposite spins is (the) old at most two electrons and then only if the electrons have b. Pauli Exclusion Principle c. Heisenberg's Uncertainty Principle d. Hund's Rule e. Schrodinger Equation ch of the following statements is faise regarding ionic compounds? Lattice energy is the gas phase. Coulomb's law describes the electrical forces of attraction between ions. a. When two ion b. bond, the net energy is lower s come together and form an ionic the change in energy that occurs when an ionic solid is formed form ions in c. d. Ca of its ions oxide has a higher metting point than potassium chloride due to the greater charge e. T he atoms in polyatomic ions are held together by covalent bonds. irvnris 8f the following electron contfiqurations is correct for the Fe on? The atomic number for iron is 26 b. e. .None of the above is correct.

Explanation / Answer

14)option b , Pauli Exclusion principle explanation: it is the definition of paulis rule 16) Fe+3 indicates 23 electrons so out of given options b is correct because it contains 23 electrons and follows Aufbau principle while filling atomic orbitals . 15) option a because the net energy is higher
