The nature of this orbital is such that the energy of repulsion between unshared pairs for the nitrogen-nitrogen triple bond is expected to be very small, whereas it is large, about 40 kcal/mole, for N N and N N; in consequence the triple bond is especially stable. For C C , on ...
Summation of the equations allows thefusionprocess to be written as a reaction among four atoms of hydrogen to yield one atom ofhelium(He), twopositrons(0+1e), and energy: this equation does not show that the process uses up and regenerates the carbon-12. In a sense, carbon acts as ...
