• Electrons can revolve only in certain definite orbits around the nucleus. (Each having fixed energy) called K, L, M, N.... • Electrons revolve only in those orbits for which angular momentum is an integral multiple of h/2π.. ie. mvr=nh/2π • Energy is emitted or absorbed only when an electron jumps from one orbit to another
The No of Electrons in this Structure: Name of this Element: Electronic Configuration: Of special Interest are transitions from Z=23->24 and 28->29
