Only certain electron transitions are allowed from one en-ergy level to another. In one-electron species, the change in the quantum number l of an allowed transition must be ±1. For ex-ample, a 3p electron can drop directly to a 2s orbital but not to a 2p. Thus, in the UV series, where nfinal1, allowed electrontransitions can start in a porbital (l=1) of n=2 or higher, notin an s(l=0) or d(l=2) orbital of n=2 or higher. From whatorbital do each of the allowed electron transitions start for the first four emission lines in the visible series (n(final=2))?
Atomic Structure
The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.
Shape of the D Orbital
Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.
