(i) Ruby (contains Cr³+ in Al2O3), red. (ii) Sapphire (contains Fe²+ and Ti4* in Al2O3), intense blue. (iii) Cr₂O7², deep orange. (iv) [WO4], colourless but shows a very strong band in the UV. (v) [Fe(bpy)3]2+, deep red.
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.
what kind of electronic transitions are responsible for the colours of the following species? For each case, state the type of the electronic transition, the orbitals between which the transition occurs and briefly explain the reason for your assignment.
