The color in KMnO4 arises from an electronic transition, but it is actually not a d-d ... When the light is reflected (or transmitted) it is missing the frequencies of the light absorbed, and so it looks pink.
Perfect gases are assumed to be comprised of infinitesimally small particles and to interact only at the point of collision. At intermediate pressures, the volume of the gas become
All electrons on the 4p sub-shell must be characterized by the quantum number(s): (1) n=4, m= 0, s= ± 1/2 (2) l=1 (3) l=0, s= ± 1/2
