1. Ultra-high-energy gamma rays interact with magnetic fields to produce positron electron pairs . 2. Before the above reaction, the sulfur atom has two lone electron pairs . 3. Say we had 1000 electron pairs between the two. 4. Ammonia is actually classified as pyramidal, as nonbonding electron pairs have a greater repulsive influence. 5. However, general chemical reactions typically involve closed-shell species and hence rearrange " electron pairs ". 6. In the meanwhile oxygen takes complete control of the electron pair and becomes negatively charged. 7. For Cooper electron pairs , " a " and " c " represent different spin directions. 8. The two dots on the P represent the lone electron pair of the phosphorus atom. 9. An alternative form of representation, not shown here, has bond-forming electron pairs represented as solid lines. 10. Normally the count of electron pairs is taken.
