Source sentences:
text: As f-f transitions are Laporte-forbidden, once an electron has been excited, decay to the ground state will be slow.
text: As such this electron would be less attracted to the nucleus and would release less energy when added.
text: Usually, the electrons in a chemical bond are more attracted to one atom (the more electronegative one) than to the other.
text: Similarly, doping silicon with a group 13 element such as boron, aluminium, or gallium results in the introduction of acceptor levels that trap electrons that may be excited from the filled valence band, creating a p-type semiconductor.
