Discuss the laporte selection rule and ways in which it can be lifted for octahedral and tetrahedral complexes (5) (b) discuss the spin selection rule and ways in which it can be lifted in some transition metal complexes (5)

It would be (at) + cu (s)

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
