(c) 1. False. The half-filled and fully-filled electronic configurations are more stable. It is due to the larger exchange energy 2. False. The symbol stands for sharp-a term used in the characterization of spectral lines. The symbols and stand for principal, diffuse, and fundamental, respectively 3. True. 4. False. The expression is Hence, energy and wavelength are inversely related |
