You measured the absorbance values at selected wavelengths for one of the complexes above. Record those values below, as well as the identity of your chosen complex. Determine your estimate for the wavelength of maximum absorbance (λmax), and show your calculations for the energy of d-orbital splitting, Δ. 0.10 M Ni(NO)2 : 10 drops approximately 0.50 mL
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.
