The colors in the copper-containing minerals malachite,which is green and has an empirical formula of Cu2CO3(OH)2, and azurite, which is blue and has an empirical formulaof Cu3(CO3)2(OH)2, come from a single d-d transitionin each compound. The compounds are sometimes foundtogether in nature as shown here. (a) What is the electronconfiguration of the copper ion in each mineral? (b) Basedon their colors, in which compound would you predict thecrystal-field splitting Δ is larger?
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.
The colors in the copper-containing minerals malachite,
which is green and has an empirical formula of Cu2CO3

of Cu3(CO3)2(OH)2, come from a single d-d transition
in each compound. The compounds are sometimes found
together in nature as shown here. (a) What is the electron
configuration of the copper ion in each mineral? (b) Based
on their colors, in which compound would you predict the
crystal-field splitting Δ is larger?
