1. the photoelectric effect is the emission of electrons or other free carriers when light is shone onto a material . Electrons emitted in this manner can be called photoelectrons
3. electrons orbitals that have the same energy levels are called degenerate orbitals .
2. if inversion through the center of symmetry in a molecule results in the same phases for the molecular orbital , then MO I said to have gerade symmetry
orbitals which have left unchanged by the operation of inversion are labelled with a subscript g , while those which undergo a change in sign are labelled u . the symbols g and u come from the German word gerade and ungerade .
4.in chemistry , an enantiomers , are also known as an optical isomers , is one of two stereoisomers that are mirror images of each other that are non- superposable , much as ones left and right hands are the same except for being reversed along one axis .
5. an atom or group whose presence is responsible for the colour of a compound ,
