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.
How many electrons does aluminum have? Well, it has 13 protons, so a neutral atom of aluminum must have 13 electrons. Which electrons are they? Well, it has two 1 s electrons, two 2 s electrons, six 2 p electrons, two 3 s electrons, and one lonely 3 p electron.hat electron is called a 1 s electron. Helium (in the very top right corner box), labeled 1 s ^2, has two electrons. Both of them are 1 s electrons. Lithium is in the box that is labeled 2 s ^1. An atom of lithium has three electrons: two 1 s electrons and a 2 s electron.
