The Allegory of the Cave. The dialogue between Socrates and Glaucon is probably fictitious and composed by Plato; whether or not the allegory originated with Socrates, or if Plato is using his mentor as a stand-in for his own idea, is unclear. In the dialogue, Socrates asks Glaucon to imagine a cave, in which prisoners are kept.
The d sublevel consists of five orbitals that can hold a maximum of  two electrons each. The total maximum number of electrons that the  d sublevel can hold is 10 electrons.
Solutions. 1  The 2s orbital would be filled before the 2p orbital because orbitals that are lower in energy are filled first. 2  There are 5 d orbitals in the d subshell. 3  A p orbital can hold 6 electrons.  Based off of the given information, n=4 and â=3.
