The allegory not only draws on the theory of forms, but it is connected both to the concept of forms and Plato's theory of the stages of life. 1  At the lowest stage, the cognitive stage of imagination (in Greek, eikasia), the prisoners exist bound and hindered in their perspective.
Since any orbital can hold a maximum of two electrons, the bonding orbital in H 2 + is only half-full. This single electron is nevertheless enough to lower the potential energy of one mole of hydrogen nuclei pairs by 270 kJ quite enough to make them stick together and behave like a distinct molecular species.
We will not fill in more than 20 electrons so donât worry about what comes next after 4s. Remember for neutral atoms, the number of protons equals the number of electrons. So for each atom note how many electrons you have and fill them in! Remember s sublevels can only hold 2 electrons, and p 6 electrons.
