To show the electron configuration for an atom, when would it be better to use an orbital notation than to use a written configuration with numbers, letters, and superscripts?

I believe it would be better to use an orbital designation than the written configuration, if the number of electrons in the ground state of the atom are quite high for the given element, as above 50, for instance.

This saves space and also one can see the discrete quantized energy levels associated with the subshells of the main energy levels if written in orbital designation.

Yes, endothermic means it turns cold. and some chemical changes include change of tempature.

Sorry i dont understand the question can you rephase it?
