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.
ow many more electrons can fit within the valence shell of a fluorine atom? 1 How is the number of unpaired valence electrons in an atom related to the number of bonds that the atom can form? The number of unpaired valence electrons in an atom is the same as the number of bonds that the atom can form. Why is it so easy for a magnesium atom to lose two electrons? Because magnesium has only two electrons in its valence shell.
